46 Capricorni is a solitary[8] star located around 790 light years away from the Sun in the southern constellation of Capricornus, near the northern border with Aquarius. It is visible to the naked eye as a dim, yellow-hued point of light with an apparent visual magnitude of +5.10.[2] 46 Cap is also known by its Bayer designation of c Capricorni (c Cap), and occasionally as c1 Capricorni to distinguish it from the nearby star c2 Capricorni.[9] It is moving closer to the Earth with a heliocentric radial velocity of −15.5 km/s.[3]
This star has received a stellar classification of G8Iab,[3] which suggests it is a G-type supergiant star, as well as G7.5II-IIICN0.5,[4] which instead indicates a luminosity class between a giant and a bright giant. Abundance analysis suggests the star has not yet passed the first dredge-up.[3] It has 4.6[6] times the mass of the Sun and has expanded to 33[3] times the Sun's radius. The star is radiating 627[6] times the luminosity of the Sun from its photosphere at an effective temperature of 4,837 K.[3]
