35 Vulpeculae is a single,[9] white-hued star in the northern constellation of Vulpecula. It is faintly visible to the naked eye with an apparent visual magnitude of 5.39.[2] An annual parallax shift of 16.9162±0.0681 mas[1] provides a distance estimate of about 193 light years. It is moving closer with a heliocentric radial velocity of −8 km/s.[4]
This is an A-type main-sequence star with a stellar classification of A1VmA3,[3] indicating it has the spectrum of an A1 class star with the metal-lines of an A3 star. It is an estimated 212[5] million years old with a projected rotational velocity of 81 km/s.[7] The star has 2.15[5] times the mass of the Sun with 1.70[6] times the Sun's radius. It is radiating 21.6[2] times the Sun's luminosity from its photosphere at an effective temperature of around 9,622 K.[5]
