13 Vulpeculae is a blue giant with a stellar classification of class B9.5III[4] in the northern constellation Vulpecula. It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 4.57[4] and it is approximately 339 light years away from the Sun based on parallax. The star is radiating 180[4] times the luminosity of the Sun from its photosphere at an effective temperature of 8,801 K.[8]
There is one reported companion, designated component B, with a magnitude of 7.37, an orbital period of roughly 615 years, and an angular separation of Script error: No such module "val"..[11] The system is moving closer to the Earth with a heliocentric radial velocity of −28 km/s.[5]
