Top 10 Largest stars in the Universe

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

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

9. Mu Cephei or Garnet Star

Mu Cephei

Mu Cephei or Garnet Star, according to Herschel, is the 9^th 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 8^th 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 sagitari

KW Sagittarii is the 7^th 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 6^th rank of largest stars in the universe and the measurement is 1,260–1,610 solar radii.

5. V354 Cephei

V354 Chepei

V354 Cephei is 5^th 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

V838 Monocerotis, 4^th largest stars ever found, is around 1,570-1970 solar radii according to The Astrophysical Journal 622, 2^nd edition on April 2005

2. VV Cephei A

VV chepei

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

VY Canis Majolaris

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?
