HD 77370 is a single 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. It is located at a distance of 85 light years from the Sun based on parallax , and is drifting further away with a radial velocity of +13 km/s.
This is an ordinary F-type main-sequence star with a stellar classification of F4V. It is around 1.3 billion years old and retains a relatively high projected rotational velocity of 60 km/s. The star has 1.45 times the mass of the Sun and 1.67 times the Sun's radius . It is radiating 4.8 times the luminosity of the Sun from its photosphere at an effective temperature of 6,699 K. The star is the most likely source of the X-ray emission detected at these coordinates.
