HD 77370 is a single[7] star in the constellation Carina. It has the Bayer designation b2 Carinae; HD 77370 is the identifier from the Henry Draper catalogue. This object has a yellow-white hue and is visible to the naked eye with an apparent visual magnitude of 5.17.[2] It is located at a distance of 85 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +13 km/s.[2]

This is an ordinary F-type main-sequence star with a stellar classification of F4V.[3] It is around 1.3[2] billion years old and retains a relatively high projected rotational velocity of 60 km/s.[5] The star has 1.45[4] times the mass of the Sun and 1.67[1] times the Sun's radius. It is radiating 4.8[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,699 K.[4] The star is the most likely source of the X-ray emission detected at these coordinates.[8]
