1. mask UY

UY shield constellation is a red Supergiant star with a radius of 65,438+0,708 suns and a volume of 5 billion suns. It is one of the largest stars discovered by people at present. If this huge, low-density red Supergiant star is placed in the position of the sun, its photosphere may engulf Jupiter's orbit.

2 canis major VY

VY is an extremely oxygen-enriched red Supergiant star in Canis Canis major, which is about 3,900 light years away from the earth and has an apparent magnitude of about 300,000 suns, ranging from 6.5 to 9.6. It is listed as a special Supergiant star because of its huge volume and unusually high loss rate of Hengxin substances.

3.antares

Antares, also known as Antares, is an alpha star located in the center of Scorpio. Through the observation of the equipment, it can be found that this famous red Supergiant star emits fiery red light, and it is also a visual binary star with a compound magnitude of about 1.58 and an absolute magnitude of -5.28, which is a bright star of 15 all day.

4. Betelgeuse

Betelgeuse is a red Supergiant star with M 1-2, with an apparent magnitude of 0.50 and an absolute magnitude of -5.85. It is about 640 light years away from the Earth. It is located in Orion, with a radius of about 887 to 955 times that of the sun. According to related research, this star, which can be observed without binoculars, will become a supernova in one million years.

5.rigel

Betelgeuse is a planet about 863 light years away from the Earth, with an apparent magnitude of about 0. 13 and an absolute magnitude of -7.92. It ranks seventh among the 20 brightest stars in the whole day, and its luminosity is1.2000 times that of the sun, making it the brightest blue Supergiant star.

6. Bi Su Wu

Bisuwu is the14th bright star in the whole day, also known as Taurus α, with an average apparent magnitude of 0.85 and an absolute magnitude of -0.64. The center of mass of this planet is about 65.3 light years away from the Earth, and it is an orange giant K5-3. The surface temperature of this planet reaches 3900 Kelvin, making it the brightest star in Taurus.

7. arcturus

Arcturus, also known as the alpha star of Capricorn, is the third brightest star in the whole night sky, with an apparent magnitude of -0.05, second only to Sirius and the old man. The center of mass of this planet is about 36.7 light years away from the earth. Although the planet is located in the northern hemisphere as a whole, it can also be observed in the southern hemisphere because it is less than 20 degrees from the equator of the celestial sphere.

8. Beihe No.3

Beihe III, also known as Gemini β, is a bright star of 17, with an apparent magnitude of 1. 14 and an absolute magnitude of about 1.08. The center of mass of this K0III orange giant is about 33.78 light years away from the Earth, and its luminosity is 43 times that of the sun. This planet is the orange giant planet closest to the earth.

9. Sirius Also known as DOG STAR

Sirius, located in Canis Canis, with an apparent magnitude of-1.46, is the brightest star in the whole day after the sun. Because of its apparent magnitude, this blue-white main sequence star has become a white dwarf observed by human beings. In addition to the main sequence star, there is also a white dwarf companion star, which is about 8.6 light years away from the earth.

10. Sun

The sun is a stellar object located in the center of the solar system, which rotates around the center of the Milky Way. It is surrounded by eight planets, asteroids, meteors, comets and interstellar dust. The size of this planet is about1.3000 times that of the earth, its diameter is about 1392000 kilometers, and its diameter is about 109 times that of the earth.
