Eta Carinae is one of the most massive binary star systems known, lying at a distance of about 7,500 light years from Earth.
Eta Carinae is located in the direction of Carina constellation. The primary component in the system has about 90 times the mass of the Sun and is 5 million times more luminous.
The smaller star has about 30 solar masses and may be up to a million times more luminous than the Sun. Both stars will reach the end of their life cycle in supernova or hypernova explosions in the relatively near future.
