17 Vulpeculae is a single,[10] blue-white hued star in the northern constellation of Vulpecula. The distance to this star can be estimated from its annual parallax shift of 6.8168±0.1430,[1] which yields a separation of roughly 480 light years. It is moving nearer with a heliocentric radial velocity of −8 km/s,[4] and will make its closest approach in around 6.1 million years at a distance of about 419 ly (128.36 pc).[2] The star is faintly visible to the naked eye with an apparent visual magnitude of 5.08.[2]

This is an ordinary B-type main-sequence star with a stellar classification of B3 V.[3] It is just 11[5] million years old with a high projected rotational velocity of 115 km/s.[8] The star has an estimated 6.1[5] times the mass of the Sun and around 3.9[6] times the Sun's radius. It is radiating 573[2] times the Sun's luminosity from its photosphere at an effective temperature of 15,648 K.[7]
