Which of the eight stars is blocked by volume, UY is the largest and Sirius is the brightest.

Speaking of the eight planets, we all know that they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Do you know what eight stars are? Next, let's take a look with me.

What are eight stars? There are actually not eight stars in size/brightness, only eight planets, but there are countless stars in the universe. It is also possible to arrange eight stars. Next, I will arrange them according to size and brightness.

(1) The eight largest stars in the Milky Way 1, UY in the shield constellation: a red Supergiant star in the shield constellation, with a radius of 1708 times that of the sun and a volume of about 4.5 billion times that of the sun, is the largest star known to mankind, ranking first in the list of the top ten stars in the Milky Way and about/kloc-from the earth.

2. Cepheid IV: Also called Cepheus? Located in Cepheus, it is a red Supergiant star with a radius of 1650 times that of the sun. It looks like garnet, so it is also called pomegranate star.

3.WOH G64: The constellation Sagittarius in the Magellanic system is a red Supergiant star with a radius of 1540 times that of the sun. This star is the oldest of the eight stars in the Milky Way. At present, it is at the end of stellar evolution, and it is expected that a supernova explosion will occur after 2000.

4. Cepheus V354: Located in Cepheus, it is a red Supergiant star with a radius of 1520 times that of the sun and 9000 light years away from the earth. In addition, Cepheus V354 is also in the final stage of evolution, which may lead to supernova explosion in the future.

5. Cygnus KY: A super red giant located in Cygnus, 5,000 light years away from the Earth, with brightness 300,000 times that of the sun and mass 25 times that of the sun. The size of this star is controversial. The radius of Cygnus KY is 1420-2850 times that of the sun.

6.KW Sagittarius: A red Supergiant star in Sagittarius is 1 0,000 light years away from the Earth, and its radius is 1 0,460 times that of the sun.

7. Cepheus RW: Located in Cepheus, it is an orange Supergiant star with a radius of 1260- 16 10 times the radius of the sun.

8. Vi Canis: A red Supergiant star among the six stars of Canis, which is 3820 light years away from the Earth, with a radius of 1.420 times that of the sun and a volume of 2.86 billion times that of the sun. It used to be the largest star in the universe, and now it ranks at the tail of the eight largest stars in the Milky Way.

(2) The eight brightest stars in the whole day and above are the eight stars arranged by volume in the Milky Way. Next, I will bring you the eight brightest stars in the whole day, with reference to the brightness of the sun: -26.72.

1, Sirius: located in Canis major, 8.6 light years away from the earth, with brightness of-1.45;

2. Canopus: located at the bottom of the ship, 80 light years away from the earth, with brightness of-0.73;

3. Nanmen II: Located in Centauri, 4.3 light years away from the Earth, with brightness of-0.10;

4. arcturus: located in Capricorn, 30 light years away from the earth, with brightness of-0.06;

5. Vega: located in Lyra, 25 light years away from the earth, with a brightness of 0.04;

6. Capella: located in Auriga, 40 light years away from the earth, with a brightness of 0.08;

7. Betelgeuse: located in Orion, 700 light years away from the earth, with a brightness of 0.11;

8. Nanhesan: Located in Canis minor, it is 1 1 light-year away from the earth, with a brightness of 0.35.

Summary: I'll stop here about the eight stars. In fact, there are many such arrangements, such as by mass, by nearest to the earth and so on. In short, the vastness of the universe is unimaginable to mankind. In addition to stars, there are neutron stars, black holes, quasars, galaxies, clusters of galaxies, and the largest structure of the universe. All this is waiting for us to explore!
