If you ask any random person, then almost everyone will answer - "". This star is without a doubt the brightest and most popular, which is why most people think that she is popular because she is the brightest. However, it is not. Polaris takes only 42nd place in brightness among the stars of the night sky.
Stars have different brightness and color. Each star has its own, to which it is attached from the moment of birth. In the formation of any star, the dominant element is hydrogen - the most abundant element in the universe - and its fate is determined only by its mass. Stars with a mass of 8% of the mass of the Sun can ignite a nuclear fusion reaction in the core, fusing helium from hydrogen, and their energy gradually moves from the inside out and pours out into the Universe. Stars of low mass, due to low temperatures red, dull, and burn their fuel slowly—the longest-lived ones are destined to burn for trillions of years. But the more a star gains mass, the hotter its core, and the larger the region in which nuclear fusion takes place. Not surprisingly, the most massive and hottest stars are also the brightest. The most massive and hottest stars can be tens of thousands of times brighter than the Sun!
What is the brightest star in the sky?
This is not as simple a question as it seems. It all depends on what you mean by the brightest star.
Speaking of the brightest star in the sky that we see- that's one thing. And if by brightness we mean the amount of light emitted by a star, then this is completely different. One star in the sky can be brighter than another simply because it is closer than the larger, brighter stars.
When they talk about the brightest star in the sky
When talking about the brightest star in the sky, it is necessary to distinguish between the apparent and absolute brightness of the stars. They are usually called the apparent and absolute stellar magnitudes, respectively.
- Apparent magnitude is the brightness of a star in the night sky as viewed from Earth.
- The absolute magnitude is the brightness of a star from a distance of 10 parsecs.
How less value magnitude, the brighter the star.
is the brightest star in the night sky
The brightest star in the sky is undoubtedly Sirius. It shines and is highly visible in the Northern Hemisphere during the winter months. The apparent stellar magnitude of Sirius is -1.46 m. Sirius is 20 times brighter than the Sun and twice as massive as it. The star is located approximately 8.6 light years from the Sun and is one of the stars closest to us. Its brilliance is the result of its true brightness and its proximity to us. 
Sirius is a double star, the brightest star in the night sky, which is part of the constellation Big Dog, also called α Canis Major. A binary star is a system of two gravitationally associated stars circulating in closed orbits around a common center of mass. The second star, Sirius B, has a magnitude of 8.4, is slightly lighter than the Sun and is the first to be discovered, and also the most massive, discovered to date. The average distance between these stars is about 20 AU. e., which is comparable to the distance from the Sun to Uranus. The age of Sirius (according to calculations) is approximately 230 million years.
Sirius A will exist on the main sequence for about 660 million more years, after which it will turn into a red giant, and then shed its outer shell and become a white dwarf. Therefore, the estimated duration life cycle Sirius A can be about 1 billion years.

- Alternative name:α Orionis
- Apparent magnitude: 0.50 (variable)
- Distance to the Sun: 495 - 640 St. years
Betelgeuse is a bright star in the constellation Orion. Red supergiant, semi-regular variable star, whose brightness varies from 0.2 to 1.2 magnitudes. The minimum luminosity of Betelgeuse is 80 thousand times greater than the luminosity of the Sun, and the maximum is 105 thousand times. The distance to the star is, according to various estimates, from 495 to 640 light years. This is one of the largest stars known to astronomers: if it is placed in the place of the Sun, then minimum size it would fill the orbit of Mars, and at the maximum it would reach the orbit of Jupiter.
The angular diameter of Betelgeuse, according to modern estimates, is about 0.055 arcseconds. If we take the distance to Betelgeuse equal to 570 light years, then its diameter will exceed the diameter of the Sun by about 950-1000 times. The mass of Betelgeuse is approximately 13-17 solar masses.

- Alternative name:α Eridani
- Apparent magnitude: 0,46
- Distance to the Sun: 69 St. years
Achernar is the brightest star in the constellation Eridani and the ninth brightest star in the entire night sky. It is located at the southern end of the constellation. Of the ten brightest stars, Achernar is the hottest and bluest. The star rotates unusually quickly around its axis, which is why it has a strong elongated shape. Achernar is a double star. As of 2003, Achernar is the least spherical star ever studied. The star rotates at a speed of 260-310 km/s, which is up to 85% of the break up velocity. Due to the high rotation speed, Achernar is strongly flattened - its equatorial diameter is more than 50% larger than its polar diameter. Achernar's axis of rotation is tilted at an angle of about 65% to the line of sight.
Achernar is a bright blue double star with total weight about eight solar. It is a main sequence star of spectral type B6 Vep, with a luminosity of more than three thousand times that of the Sun. Distance from star to solar system- about 139 light years.
Observations of the star with the VLT have shown that Achernar has a companion orbiting at a distance of about 12.3 AU. and rotating with a period of 14-15 years. Achernar B is a star with a mass of about two solar masses, spectral type A0V-A3V.
The name comes from the Arabic آخر النهر (ākhir an-nahr) - "end of the river" and most likely originally belonged to the star θ Eridani, which bears its own name Akamar with the same etymology.

- Alternative name:α Small Dog
- Apparent magnitude: 0,38
- Distance to the Sun: 11.46 St. years
To the naked eye, Procyon looks like a single star. In fact, Procyon is a binary star system consisting of a main sequence white dwarf called Procyon A and a faint white dwarf called Procyon B. Procyon looks so bright not because of its luminosity, but because of its proximity to the Sun. The system is located at a distance of 11.46 light years (3.51 parsecs) and is one of our closest neighbors.
The origin of the name Procyon is very interesting. It is based on long observation. Literal translation from Greek " before Dog", more literary -" the harbinger of the dog. The Arabs called him - "Sirius, shedding tears." All names have a direct connection with Sirius, who was worshiped by many ancient peoples. It is not surprising that observing starry sky, they noticed the harbinger of the rising Sirius - Procyon. He appears in the sky 40 minutes earlier, as if running ahead. If you imagine Canis Minor in the picture, then Procyon should be looked for in its hind legs.
Procyon shines like 8 of our Suns and is the eighth brightest star in the night sky, the luminosity is 6.9 times greater than that of the Sun. The mass of the star is 1.4 times the mass of the Sun, and the diameter is 2 times. It is moving towards the solar system at a speed of 4500 m per second
Finding Procyon is not difficult. To do this, you need to face south. Find the belt of Orion with your eyes and draw a line from the lower star of the belt to the east. You can navigate by the larger constellation Gemini. In relation to the horizon, the Small Dog is below them. And finding Procyon in the constellation Canis is not difficult, because it is the only bright object, and it attracts with its radiance. Since the constellation Canis Minor is equatorial, that is, it rises quite low above the horizon, in different time year it rises in different ways and best time for his observations - winter.

- Alternative name:β Orionis
- Apparent magnitude: 0.12 (variable)
- Distance to the Sun:~870 St. years
With an apparent magnitude of 0.12, Rigel is the seventh brightest star in the sky. Its absolute magnitude is -7 and it is located at a distance of ~870 light-years from us.
Rigel has a spectral class of B8Iae, a surface temperature of 11,000 Kelvin, and its luminosity is 66,000 times greater than that of the Sun. The star has a mass of 17 solar masses and a diameter 78 times that of the Sun.
Rigel is the brightest star in our local area Milky Way. A star is so bright that if viewed from a distance of one astronomical unit (the distance from the Earth to the Sun), it will shine like an extremely bright ball with angular diameter 35° and apparent magnitude -32 (for comparison: apparent magnitude is −26.72). The power flow at this distance will be the same as from a welding arc from a distance of a few millimeters. Any object so close will be vaporized by the strong stellar wind.
Rigel is a famous binary star, which was first observed by Vasily Yakovlevich Struve in 1831. Although Rigel B has a relatively faint magnitude, its proximity to Rigel A, which is 500 times brighter, makes it one of the targets of amateur astronomers. According to calculations, Rigel B is removed from Rigel A at a distance of 2200 astronomical units. Due to such a colossal distance between them, there is no sign of orbital motion, although they have the same proper motion.
Rigel B itself is a spectroscopic binary consisting of two main sequence stars orbiting a common center of gravity every 9.8 days. Both stars belong to the spectral class B9V.
Rigel is a variable star, which is not common in supergiants, with a magnitude range of 0.03-0.3, changing every 22-25 days.

- Alternative name:α Aurigae
- Apparent magnitude: 0,08
- Distance to the Sun: 42.6 St. years
Capella is the brightest star in the constellation Auriga, the sixth brightest star in the sky and the third brightest in the sky of the Northern Hemisphere.
Capella (lat. Capella - "Goat"), also Capra (lat. Capra - "goat"), Al Khayot (Arabic العيوق - "goat") - a yellow giant. In the drawing of the constellation, Capella is located on the shoulder of the Auriga. On sky maps, a goat was often drawn on this shoulder of the Charioteer. It is closer to the north pole of the world than any other star of the first magnitude (the North Star is only of the second magnitude) and therefore plays an important role in many mythological tales.
From an astronomical point of view, Capella is interesting in that it is a spectroscopic binary star. Two giant stars of spectral type G, with a luminosity of about 77 and 78 solar, are 100 million km apart (2/3 of the distance from the Earth to the Sun) and rotate with a period of 104 days. The first and fainter component - Capella Aa has already evolved from the main sequence and is at the stage of a red giant, helium burning processes have already begun in the interior of the star. The second and brighter component, Capella Ab, also left the main sequence and is on the so-called “Hertzsprung gap” - a transitional stage in the evolution of stars, in which the thermonuclear synthesis of helium from hydrogen in the core has already ended, but helium combustion has not yet begun. Capella is a source of gamma radiation, possibly due to magnetic activity on the surface of one of the components.
The masses of the stars are approximately the same and amount to 2.5 solar masses for each star. In the future, due to the expansion to the red giant, the shells of the stars will expand and, quite likely, will come into contact.
The central stars also have a faint companion, which, in turn, is itself a double star, consisting of two class M stars - red dwarfs revolving around the main pair in an orbit with a radius of about one light year.
Capella was the brightest star in the sky from 210,000 to 160,000 BC. e. Prior to this, the role of the brightest star in the sky was played by Aldebaran, and after that by Canopus.

- Alternative name:α Lyra
- Apparent magnitude: 0.03 (variable)
- Distance to the Sun: b> 25.3 St. years
In summer and autumn, in the night sky, in the northern hemisphere of the celestial sphere, the so-called Great Summer Triangle can be distinguished. This is one of the most famous asterisms. We already know that it includes the familiar Deneb and Altair. They are located "lower", and at the top of the Triangle is Vega - a bright blue star, which is the main one in the constellation Lyra.
Vega is the brightest star in the constellation Lyra, the fifth brightest star in the night sky and the second (after Arcturus) in the Northern Hemisphere. Vega is at a distance of 25.3 light year from the Sun and is one of the brightest stars in its vicinity (at a distance of up to 10 parsecs). This star has a spectral type of A0Va, a surface temperature of 9600° Kelvin, and its luminosity is 37 times greater than that of the Sun. The mass of the star is 2.1 solar masses, the diameter is 2.3 times that of the Sun.
The name "Vega" comes from an approximate transliteration of the word waqi ("falling") from the phrase Arab. النسر الواقع (an-nasr al-wāqi‘), meaning “falling eagle” or “falling vulture”.
Vega, sometimes referred to by astronomers as "probably the most important star after the Sun," is currently the most studied star in the night sky. Vega was the first star (after the Sun) to be photographed and also the first star to have its emission spectrum determined. Also, Vega was one of the first stars to which the distance was determined by the parallax method. The brightness of Vega has long been taken as zero when measuring stellar magnitudes, that is, it was a reference point and was one of the six stars that underlie the scale of UBV photometry (measurement of star radiation in various spectral ranges).
Vega rotates very quickly around its axis, at its equator the rotation speed reaches 274 km / s. Vega spins a hundred times faster, resulting in an ellipsoid of revolution. The temperature of its photosphere is not uniform: the maximum temperature is at the pole of the star, and the minimum temperature is at the equator. At present, from Earth, Vega is observed almost from the pole, and therefore it appears as a bright blue-white star. AT recent times asymmetries have been identified in the disk of Vega, indicating the possible presence of at least one planet near Vega, the size of which may be approximately the size of Jupiter.
In the XII century BC. Vega was the North Star and will be again in 12,000 years. The "change" of the Polar stars is connected with the phenomenon of the precession of the earth's axis.

- Alternative name:α Bootes
- Apparent magnitude:−0.05 (variable)
- Distance to the Sun: 36.7 St. years
Arcturus (Alramech, Azimech, Colanza) is the brightest star in the constellation Bootes and the northern hemisphere and the fourth brightest star in the night sky after Sirius, Canopus and the Alpha Centauri system. The apparent magnitude of Arcturus is −0.05m. It enters the Arcturus stellar stream, which, according to Ivan Minchev of the University of Strasbourg and his colleagues, arose as a result of the absorption of another galaxy by the Milky Way about 2 billion years ago.
Arcturus is one of the brightest stars in the sky and therefore easy to find in the sky. Visible anywhere the globe north of 71° south latitude, due to its slight northerly declination. To find it in the sky, you need to lay an arc through the three stars of the bucket handle Ursa Major- Aliot, Mizar, Benetnash (Alkaid).
Arcturus is an orange giant of spectral type K1.5 IIIpe. The letters "pe" (from the English peculiar emission) mean that the spectrum of the star is atypical and contains emission lines. In the optical range, Arcturus is more than 110 times brighter than the Sun. From observations it is assumed that Arcturus is a variable star, its brightness changes by 0.04 magnitude every 8.3 days. As with most red giants, the reason for the variability is the pulsation of the star's surface. Radius - 25.7 ± 0.3 solar radii, surface temperature - 4300 K. The exact mass of the star is unknown, but most likely close to solar mass. Arcturus is now at that stage of stellar evolution, in which our daylight star will be in the future - in the red giant phase. The age of Arcturus is about 7.1 billion years (but not more than 8.5 billion)
Arcturus, like more than 50 other stars, is in the Arcturus stream, which brings together stars of different age and metallicity level, moving with similar speed and direction. Given the high speeds of the stars, it is possible that in the past they were captured and absorbed by the Milky Way along with their parent galaxy. Therefore, Arcturus, one of the brightest and relatively close stars to us, may have an extragalactic origin.
The name of the star comes from other Greek. Ἀρκτοῦρος, ἄρκτου οὖρος, "Guardian of the Bear". According to one version of the ancient Greek legend, Arcturus is identified with Arkad, who was placed in the sky by Zeus to protect his mother, the nymph Callisto, who was turned by Hera into a bear (the constellation Ursa Major). According to another version, Arkad is the constellation of Bootes, the brightest star of which is Arcturus.
In Arabic, Arcturus is called Haris-as-sama, "keeper of the heavens" (see Haris).
In Hawaiian, Arcturus is called Hokulea (gav. Hōkūle’a) - “star of happiness”, in the Hawaiian Islands it culminates almost exactly at its zenith. Ancient Hawaiian navigators relied on its height when they sailed to Hawaii.

- Alternative name:α Centauri
- Apparent magnitude: −0,27
- Distance to the Sun: 4.3 St. years
Alpha Centauri is a double star in the constellation Centaurus. Both components, α Centauri A and α Centauri B, are visible to the naked eye as a single star −0.27m, making α Centauri the third brightest star in the night sky. Most likely, this system also includes the red dwarf Proxima or α Centauri C, invisible to the naked eye, which is separated from the bright double star by 2.2°. All three are the closest stars to the Sun, and on this moment The proxima is somewhat closer than the others.
α Centauri has proper names: Rigel Centaurus (romanization of Arabic رجل القنطور - “foot of the Centaur”), Bungula (possibly from Latin ungula - “hoof”) and Toliman (possibly from Arabic الظلمان [al-Zulman] “Ostriches”), but they are rarely used.
The first star, Centauri A, is very similar to the Sun. There is a cold thin layer in the atmosphere. The mass of Alpha is 0.08 more than the mass of the Sun, it shines brighter and hotter. She is often reproached that she obscures Beta Centauri, but thanks to the dual union, her girlfriends are visible in the sky.
The second star - Centaurus B is 12% smaller than the Sun, therefore, it is colder. It is separated from Centaurus A by a distance of 23 astronomical units. The stars are highly interconnected. The forces of mutual attraction affect the processes occurring on the surfaces, as well as the formation of planets. Centauri B rotates relative to Centauri A. The orbit looks like a highly elongated ellipse. The turnover takes 80 years, which is very fast on a cosmic scale.
The third component of the system is the star Proxima Centauri. The name of the star means "nearest". It got its name because, thanks to its orbit, it approaches the Earth as close as possible. An object of the eleventh magnitude. Proxima revolves around two stars in 500 thousand years. According to some sources, the rotation period reaches a million years. Its temperature is very low in order to heat nearby objects, so the planets near it are not searched for. Proxima is a red dwarf that sometimes produces very powerful flares.
Get on modern spaceship to Alpha Centauri is possible in 1.1 million years, so this will not happen in the near future.
2
- Alternative name:α Carina
- Apparent magnitude: −0,72
- Distance to the Sun: 310 St. years
The star Canopus or Alpha Carina is the brightest star in the constellation Carina. With an apparent magnitude of -0.72, Canopus is the second brightest star in the sky. Its absolute magnitude is -5.53, and it is 310 light years away from us.
Canopus has a spectral class of A9II, a surface temperature of 7350° Kelvin, and a luminosity 13,600 times that of the Sun. The star Canopus has a mass of 8.5 solar masses and a diameter 65 times that of the Sun.
The diameter of the star Canopus is 0.6 AU, or 65 times that of the Sun. If Canopus were located at the center of the solar system, then its outer edges would extend three-quarters of the way to Mercury. The Earth had to be removed to a distance of three times the orbit of Pluto in order for Canopus to look in the sky just like our Sun.
Canopus is a supergiant of spectral type F and, when viewed with the naked eye, has White color. With a luminosity 13,600 times that of the Sun, Canopus is, in fact, the brightest star, up to 700 light-years from the solar system. If Canopus were located at a distance of 1 astronomical unit (the distance from the Earth to the Sun), then it would have an apparent magnitude of -37.

- Alternative name:α Canis Major
- Apparent magnitude: −1,46
- Distance to the Sun: 8.6 St. years
The brightest star in the night sky is undoubtedly Sirius. It shines in the constellation Canis Major and is highly visible in the Northern Hemisphere during the winter months. Although its luminosity exceeds the luminosity of the Sun by 22 times, it is by no means a record in the world of stars - the high visible brightness of Sirius is due to its relative proximity. In the Southern Hemisphere, it is visible during summer, north of the Arctic Circle. The star is located approximately 8.6 light years from the Sun and is one of the stars closest to us. Its brilliance is the result of its true brightness and its proximity to us.
Sirius has a spectral type of A1Vm, a surface temperature of 9940° Kelvin, and a luminosity 25 times that of the Sun. The mass of Sirius is 2.02 solar masses, the diameter is 1.7 times greater than that of the Sun.
Back in the 19th century, astronomers, when studying Sirius, drew attention to the fact that its trajectory, although it is a straight line, is subject to periodic fluctuations. In the projection of the starry sky, it (the trajectory) looked like a wavy curve. Moreover, its periodic fluctuations could be detected even in a short period of time, which in itself was already surprising since we were talking about stars - which are billions of kilometers away from us. Astronomers have suggested that a hidden object that revolves around Sirius with a period of about 50 years is to blame for such “wobbles”. 18 years after a bold assumption, near Sirius, it was possible to discover a small star, which has a magnitude of 8.4 and is the first discovered white dwarf, moreover, also the most massive one discovered to date.
The Sirius system is about 200-300 million years old. Initially, the system consisted of two bright bluish stars. The more massive Sirius B, consuming its resources, became a red giant, after which it ejected its outer layers and became a white dwarf about 120 million years ago. Sirius is colloquially known as the "Dog Star", reflecting his belonging to the constellation Canis Major. The sunrise of Sirius marked the flood of the Nile in Ancient Egypt. The name Sirius comes from the ancient Greek "luminous" or "hot".
Sirius is brighter than the nearest star to the Sun - Alpha Centauri, or even supergiants such as Canopus, Rigel, Betelgeuse. Knowing the exact coordinates of Sirius in the sky, it can be seen with the naked eye and during the day. For the best viewing, the sky must be very clear and the Sun low on the horizon. Currently, Sirius is approaching the solar system at a speed of 7.6 km / s, so over time, the apparent brightness of the star will slowly increase.
Many in November are asking the question: what is the bright star seen in the east in the morning? She really very bright: other stars pale in comparison. It is still easily distinguishable even when here, in the southeast, the dawn is already in full swing, washing away other stars from the sky. And then, almost until sunrise, this star remains completely alone.
I want to congratulate you - you are observing the planet Venus, The brightest luminary in our sky after the Sun and the Moon!
Venus is only visible in the morning or evening sky- you will never see her late at night in the south. Her time is the pre-dawn or twilight evening hours, when she literally reigns in the sky.
Check yourself if you are really observing Venus.
- November and December 2018 Venus is visible in the morning in the east rising 4 hours before sunrise. She is visible for two hours dark sky, and another hour - against the background of the morning dawn.
- The color of Venus is white, may be slightly yellowish near the horizon.
- Venus doesn't flicker that is, it does not blink, does not tremble, but shines powerfully, evenly and calmly.
- Venus is so bright that it no longer looks like a star, but like a searchlight of an airplane flying towards. It has long been noticed that the bright white light of the planet is capable of cast clear shadows on the snow; the easiest way to check this is outside the city on a moonless night, where the light of Venus is not interfered with by lanterns. By the way, according to Russian astronomers, about 30% of reports of UFOs in our country fall on the ascending or setting Venus.
Venus is still bright and visible against the background of the dawn, although the stars are almost invisible at this time. Pattern: stellarium
In November 2018 - slightly to the right of the planet. Please note: Spica is one of the twenty brightest stars in the entire sky, but next to Venus it simply fades! Another bright star, Arcturus, is above and to the left of Spica. Arcturus has a characteristic reddish color. So, Venus is much brighter and Arcturus, and even more so Spica!
Observe these luminaries for a few minutes and compare them appearance with Venus. Notice how much more flickering bright stars than Venus. Spica can even overflow different colors! Try also to remember the brightness of Venus in comparison with the brightest stars - and you will never confuse it with anything else.
Few things can match the beauty of Venus in the sky! The planet looks especially beautiful against the backdrop of a rising dawn. Beautiful celestial pictures are obtained when the crescent moon is next to Venus. The nearest such meeting will happen on the morning of December 3 and 4, 2018. Do not miss!

> The brightest star in the sky
Sirius is the brightest star: the meaning of the name Alpha Canis Major, characteristics and description with a photo, distance from the Earth, detection, a list of the brightest stars.
Among all the stars known to us, the brightest in the sky is Sirius, which is also called the “Star of the Dog”. Official name- Alpha Canis Major, located in the constellation of the same name.
Sirius is a binary system with a main sequence (A) star whose apparent magnitude reaches -1.46. It is 8.7 light years away from us and is closest to Earth.
In 1844, Friedrich Bessel noticed that the orbital path of Sirius A is a bit like a wave, which means there may be a weak satellite nearby. Alvan Clark confirmed this in 1862. We are talking about Sirius B - a white dwarf that can be seen in a large telescope (it has little effect on the overall brightness of the system).
But there are other stars near us, why is Sirius the brightest? The fact is that most stars belong to the category of red dwarfs. They are not only small, but also dull. In fact, the closest red dwarf is Proxima Centauri. It's M-type less G-type(Sun). The brightest is A-type (Sirius).
The starry sky can captivate for life thanks to its bright lights. Even with the naked eye, you can see that some objects shine brighter than others. Scientists measure the brightness of celestial bodies using a scale. The smaller the object itself, the brighter it will be.
List of brightest stars in the sky
We know which star is the brightest for an earthly observer. However, other bright celestial bodies can be found in space. You will be able to admire most bright stars in the sky and their "apparent magnitudes" (as they are seen towards the Earth). Use our online star chart to find them yourself with a telescope.
