79 Cancri
G-type star in the constellation Cancer
79 Cancri is a star in the constellation Cancer, located 400 light years from the Sun.[1] It is just visible to the naked eye as a dim, yellow-hued star with an apparent visual magnitude of 6.04.[2] This object is gradually moving slower to the Earth with a heliocentric radial velocity of −3.2 km/s.[1]
This is an aging giant star with a stellar classification of G5 III,[3] which indicates that, at the age of 770[4] million years, it has exhausted the hydrogen at its core and evolved away from the main sequence. The star has 2.30[4] times the mass of the Sun and has expanded to 9.4[1] times the Sun's radius. It is radiating 58[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 5,076 K.[4]
