The Closest star from our planet, the sun, is the family of countless stars where some or could be millions of them far larger and far brighter than the sun. in this post, we are going to study top 10 largest star in the universe. As information, the stars are measured with Solar radius standard ( 1 Solar Radii is equal to 695,500 kilometres /432,450 miles/0.004652 AU ( Astronomical units). Our lovely star, the Sun, is too tiny to be compared with the smallest of top 10 largest stars below and it look insignificant
10. Betelgeuse or Alpha Orionis
Betelgeuse is 950–1,000 solar radii (according to Graham M. Harper at Astronomical Journal) or 880–988 solar radii (according to Jim Kaler in 2009). The weight of the star is 18–19 solar mass and it has luminosity 180,000x brighter than he Sun
Mu Cephei or Garnet Star, according to Herschel, is the 9th biggest star in the universe and the size is 1,420 solar radii according to The Astrophysical Journal 628 on August 2005.
8. KY Cygni
Same as MU Cephei, according to the The Astrophysical Journal, the size of the star is 1,420–2,850 solar radii. This 8th biggest star is 300,000 brighter than sun and it can be located on the constellation Cygnus. From the earth, the distance is around 5,000 light-years away
7. KW Sagittarii
KW Sagittarii is the 7th largest in the universe. The size is 1,460 solar radii according to the Astrophysical Journal 628.
6. RW Cephei
RW Cephei stays on the 6th rank of largest stars in the universe and the measurement is 1,260–1,610 solar radii.
5. V354 Cephei
V354 Cephei is 5th biggest starts in the universe and the measurement is around 1,520 solar radii.
4. WOH G64
WOH G64 is 1,540 solar radii wide according to Philip Massey, Bertrand Plez , Emily M. Levesque, and Knut A. G. Olsen on June 2009 on Astronomical Journal 137 title “The Physical Properties of the Red Supergiant WOH G64: The Largest Star Known?”.
3. V838 Monocerotis
V838 Monocerotis, 4th largest stars ever found, is around 1,570-1970 solar radii according to The Astrophysical Journal 622, 2nd edition on April 2005
2. VV Cephei A
VV Cephei A is 1,600–1,900 solar radii according to Professor James B. (Jim) Kaler from University of Illinois on March 2010. The weight is estimated 100x solar mass (1 solar mass= 1.98892 × 1030 kilograms).The star resides on the constellation Cepheus, 2,400 light years from our planet
1. VY Canis Majoris
The biggest star on the universe is so big and the sequence is contradicted with Stellar evolutionary theory. It is the largest star among other stars on the Constellation Canis Major and the size is around 1,800-2,100 solar radii (according to Astronomical Society of Japan, 16 July, 2010). The surface is spanning 2.7 billion km/ 1.7 billion miles. It is 30-40X heavier than Sun. VY Canis Mayoris is equal to 7,000,000,000,000,000 Earths.
If the star is habitable and you can go there, do you want to stay on the largest star in the universe?
