Star in the constellation Vulpecula
17 Vulpeculae is a single, 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, which yields a separation of roughly 480 light years . It is moving nearer with a heliocentric radial velocity of −8 km/s, and will make its closest approach in around 6.1 million years at a distance of about 419 ly (128.36 pc). The star is faintly visible to the naked eye with an apparent visual magnitude of 5.08.
This is an ordinary B-type main-sequence star with a stellar classification of B3 V. It is just 11 million years old with a high projected rotational velocity of 115 km/s. The star has an estimated 6.1 times the mass of the Sun and around 3.9 times the Sun's radius . It is radiating 573 times the Sun's luminosity from its photosphere at an effective temperature of 15,648 K.
