Wednesday, May 11th 2011. | Largest

For species on earth, Sun is source of power. It is big, mighty, grace and sometimes arrogant. In our solar system, sun might be the only one. However, in the Galaxy, Sun is mere dust in the sand. On universe, countless stars floating on the airless space and they are fatter, bigger, and more powerful than the sun. On the following list, we are going to discover 10 largest star in the universe. Sun is not included. These stars is measured using standard one solar radius (Solar radii), which is 695,500km or 432,450 miles or 0.004652 Astronomical units (AU)

10. Betelgeuse or Alpha Orionis

Betelgeuse or Alpha Orionis

According to Graham M. Harper, Alpha Orionis has diameter 950-1000 solar radii. It is 880-988 solar radii according to Jim kaler. It is estimated that the weight of Betelgeuse is 18-19 solar mass. From Hubble observation, Betelgeuse is 180 thousand times brighter than our Sun.
9. RW Cephei
RW Cephei is classified in the list of red hypergiant star. It circles on the constellation Cepheus. It is estimated 1650 solar radii wide, has mass 40 solar mass and solar luminosity 770 thousand.
8. KW Sagittarii
KW Sagittarrii circles on a constellation Sagittarius approximately 10 thousand light year from the Sun. The red supergiant is 1460 solar radii wide and is 360,000 brighter than sun

7. KY Cygni

Ky Cygni is a red supergiant star circles on constellation Cygnus. It has estimated 25 solar mass and 1,420 times wider than the sun. The light of KY Cygni is 300 thousand brighter than the sun and the surface temperature is around 3,500 Kelvin
6. V354 Cephei
V354 Cephei is a red giant superstar located on same galaxy of the sun or Milky Way. The distance between sun and RW Cephei is around 9000 light years. The diameter is 1520 bigger than the sun and it has luminosity 3650 times brighter than the sun.
5. WOH G64
WHO G64 is a unique red hypergiant star that floats inside large Magellanic cloud. The diameter is 2000 times bigger than sun or around 2,785,000,000 km. The brightness is 2.8×105 than earth. From the sun the distance of the star is 163,000 light year away.
4. MU Cephei or Herschel’s Garnet Star
MU Cephei or Herschel’s Garnet Star is a red hypergiant star located in our Milky Way galaxy. It is the brightest star in Milky Way and one of the biggest. The mass is estimated 15 solar mass and solar luminosity is 6 × 104.
3. V838 Monocerotis
V838 Monocerotis is a red variable star, which floats in the constellation of Monoceros. The distance from the sun is estimated 20,000 light years away. The solar radius is around 1,570. Inside V838 Monocerotis ring, we can find view variable stars which resembles to the main star
2. VV Cephei
VV Cephei or also called HD 208816 is an eclipsing binary star floating in constellation Cepheus. The exact location is around 2,400 light years from our planet. VV Cephei has mass 100 solar mass, 1600-1900 solar radius, and luminosity 275,000 up to 575,000 brighter than sun
1. VY Canis Majoris

VY Canis Majoris

VV Canis Majoris or VY CMa is today’s biggest known star in the universe and one of the brightest red hypergiant. It circles on constellation Canis Mayor. The diameter is around 1800 and 2100 solar radii or 3.063 billion km or 1.7 billion miles or 3.06 terametre. The bright is 450,000 solar luminosity and the surface temperature is around 3000 Kelvin. Can you imagine how bright is our largest star in the universe?
