Top 10 Largest Stars in the Universe
The sun is the main energy source for Earth. The sun is a star that is closest to our planet Earth. Nearest star after the Sun is Alpha Centauri. Stars are celestial bodies that can emit its own light. Star when viewed from the Earth must have looked small. Actually they have a very large size than you think. Below is the largest star in the universe.
10. Antares (Alpha Scorpii)
Antares is a red super giant star in the Milky Way galaxy and the sixteenth brightest star in the night sky (sometimes listed as the light of the fifteenth, when two bright components of the Capella quadruple star system is counted as one star). Along with Aldebaran, Spica, and Regulus is one of four bright stars near the ecliptic. Antares is a slow variable star with an average size of 1.09.
9. Betelgeuse (Alpha Orionis)
Betelgeuse is a semiregular variable star is clearly the amount ranges between 0.2 and 1.2, the most for each of the first stars. This is the ninth brightest star in the night sky which lies about 640 light years from Earth. Although given the Bayer designation Alpha Orionis (a Orionis / a Ori), Betelgeuse is the second star in the constellation Orion, but light, outshone by Rigel (Beta Orionis) is almost all the time. Stars mark the top right point and the center of the Winter Triangle Winter Hexagon.
8. KY Cygni
KY Cygni is the Super Giant red star (spectral class M3m) located in the constellation Cygnus. Eight of these are the largest known star, about 1420 times the diameter of the sun, and also one of the brightest, with about 300,000 times the luminosity of the Sun. It is some 5,200 light-years.
7. KW Sagittarii
KW Sagittarii is a red hypergiant, located approximately between 9.000 to 13.000 light years from the Sun. It is 1460 in diameter of the sun, actually seven largest known stars, is 370,000 times the luminosity of the Sun. Located in the constellation Sagittarius.
6. RW Cephei
RW Cephei is a red hypergiant M-class star in the constellation Cepheus. Six of the largest known star, RW Cephei estimated 1.260 to 1.610 solar radii. RW Cephei, while nearly as large as the orbit of Jupiter, is not as large as the other stars in the constellation Cephus, namely V354 Cephei and VV Cephei A.
5. V354 Cephei
V354 Cephei is a red hypergiant stars (pulsating variable star) located in the Milky Way. Located about 9,000 light years from our sun, and is currently regarded as the fifth largest stars known, with an estimated radius 1520 times the Sun, or 1,057,160,000 miles. Assuming the estimated size is correct, if placed in the center of our solar system, it will extend to 7 AU (between the orbits of Jupiter and Saturn).
4. Woh G64
Woh G64 is a red hypergiant Large Magellanic Cloud. With 2000 times the radius of the Sun. Woh size G64 In 1540 the solar radius is estimated to 2.785 billion miles.
3. Mu Cephei
Mu Cephei stars also known as Herschel’s Garnet, is a red supergiant star in the constellation Cepheus. In 1550 solar radii this is one of the largest and most luminous stars known in the Milky Way. It seems that ruby and M2Ia given spectral class.
2. VV Cephei A
VV Cephei, also known as HD 208816, was eclipsing binary star system located in the constellation Cepheus, In between 1.600 to 1.900 solar radii about 2,400 light years from Earth. A red hypergiant system fills the Roche lobe when closest to the blue companion star, the latter appears to be on the main sequence. Matter flows from hypergiant red to blue friend.
1. VY Canis Majoris
VY Canis Majoris (V CMA) is a red star hypergiant located in the constellation Canis Major. In between 1800 and 2100 solar radii (about 2.7 billion kilometers or 1.7 billion miles), it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6 × 1016 km) or about 4900 light years from Earth. Unlike most massive stars, which occur either in double or multiple star systems, vv CMA is a single star. It is classified as a semiregular variable and has an estimated period of 2000 days. VY Canis Majoris is the largest star in universe.
