6 Corvi is a single^[9] star in the southern constellation of Corvus,^[8] located 341 light years away from the Sun.^[2] It is visible to the naked eye as a faint, orange^[10]-hued star with an apparent visual magnitude of 5.66.^[1] This object is moving closer to the Earth with a heliocentric radial velocity of −2.4 km/s.^[2] It is an evolved giant star with a stellar classification of K1 III.^[3] The star has expanded to 13.8 times the Sun's radius and is radiating 69 times the luminosity of the Sun from its enlarged photosphere^[5] at an effective temperature of 5,200 K.^[6]
