How hot does Eta Carinae get?
15,000 K Eta Carinae A/Surface temperature In 2005 astronomers studying far-ultraviolet spectral observations of Eta Carinae made by spacecraft found that it is a binary star system with an orbital period of 5.54 years. Its A component has a temperature of about 15,000 K; its B component, about 35,000 K.
Is Eta Carinae the biggest star?
Estimated to be 100 times more massive than our Sun, Eta Carinae may be one of the most massive stars in our Galaxy. It radiates about five million times more power than our Sun.
Can you see Eta Carinae?
Its location at around 60°S in the far southern celestial hemisphere means it cannot be seen by observers in Europe and much of North America. Located between Canopus and the Southern Cross, Eta Carinae is easily pinpointed as the brightest star within the large naked eye Carina Nebula.
