Eta Carinae (η Carinae or η Car) is a stellar system in the constellation Carina about 7500 to 8000 light-years from the Sun. The system contains at least two stars of which the primary is a luminous blue variable (LBV) that initially had around 150 solar masses of which it has lost at least 30. A hot supergiant of approximately 30 solar masses orbits the primary although an enormous thick red nebula surrounding Eta Carinae optically conceals this companion.
