  • the monster Eta Carinae
  • 4 million times as bright as the Sun.
  • But Eta Carinae is so large that it casts off 500 times the mass of the Earth every year.
  • The largest known star is VY Canis Majoris; a red hypergiant star in the constellation Canis Major, located about 5,000 light-years from Earth.
  • Placed in our Solar System, its surface would extend out past the orbit of Saturn. Light takes more than 8 hours to cross its circumference!
