6 Corvi

6 Corvi is a single[6] star in the southern constellation of Corvus,[5] located 341 light years away from the Sun.[1] It is visible to the naked eye as a faint, orange[7]-hued star with an apparent visual magnitude of 5.66.[2] This object is moving closer to the Earth with a heliocentric radial velocity of −2.4 km/s.[1] It is an evolved giant star with a stellar classification of K1 III.[3] The star has expanded to 13.6 times the Sun's radius and is radiating 75.5[1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,608 K.[4]
