32 Vulpeculae is a single[8] star located around 610[1] light years away from the Sun in the northern constellation Vulpecula,[7] a few degrees south of the border with Cygnus. It is visible to the naked eye as a faint, orange-hued star with a typical apparent visual magnitude of 5.03.[2] This object is drifting further away from the Earth with a heliocentric radial velocity of +6 km/s.[2]

This is an aging red giant[4] star with a stellar classification of K4 III,[5] having exhausted the supply of hydrogen at its core then expanded to 54[1] times the Sun's radius. It is a suspected variable of unknown type, with a visual magnitude that has been measured ranging from 4.99 down to 5.06.[3] The star is radiating 708[1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,041 K.[1]
