What type of star is ETA?
Eta Carinae, also called Homunculus Nebula, peculiar red star and nebula about 7,500 light-years from Earth in the southern constellation Carina and now known to be a binary star system. It is one of a small class of stars called luminous blue variables.
Is Eta Carinae a blue star?
Blue stars are stars that have at least 3 times the mass of the Sun and up. Rigel puts out about 40,000 times the energy of the Sun. An even more extreme example of a blue star is the blue supergiant Eta Carinae, located about 8,000 light-years away in the Carina constellation.
What star is Corina?
Carina is famous as the home of the bright star Canopis. It is the brightest star in the constellation and the second brightest star in the night sky with a visual magnitude of -0.74. It is a blue-white supergiant star that is 13,600 times brighter than the Sun. It is located approximately 310 light years from Earth.
Is Eta Carinae the hottest star?
Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
