V357 Carinae (a Car, a Carinae) is a spectroscopic binary in the constellation Carina. It is approximately 419 light years from Earth. The mean apparent magnitude of the system is +3.43.
V357 Carinae is composed of two similar blue-white B-type subgiants. This star has five times the radius of the Sun.[1] It is an eclipsing binary. Due to the eclipses, it is a variable star and its brightness varies from magnitude +3.41 to +3.44 with a period of 6.75 days, which is its orbital period.
