}}{{Starbox end}}17 Vulpeculae is a single,[19] blue-white hued star in the northern constellation of Vulpecula. The distance to this star can be estimated from its annual parallax shift of {{Val|6.47|0.27}},[1] which yields a separation of roughly 500 light years. It is moving nearer with a heliocentric radial velocity of −8 km/s,[6] and will make its closest approach in around 6.1 million years at a distance of about {{Convert|128.36|pc|ly|order=flip|abbr=on|sigfig=3}}.[3] The star is faintly visible to the naked eye with an apparent visual magnitude of 5.08.[3]This is an ordinary B-type main-sequence star with a stellar classification of B3 V.[4] It is just 11[11] million years old with a high projected rotational velocity of 115 km/s.[16] The star has an estimated 6.1[11] times the mass of the Sun and around 3.9[12] times the Sun's radius. It is radiating 573[3] times the Sun's luminosity from its photosphere at an effective temperature of 15,648 K.[14] References1. ^1 2 3 4 5 6 {{citation | title=Validation of the new Hipparcos reduction | last1=van Leeuwen | first1=F. | postscript=. | journal=Astronomy and Astrophysics | volume=474 | issue=2 | pages=653–664 | year=2007 | arxiv=0708.1752 | bibcode=2007A&A...474..653V | doi=10.1051/0004-6361:20078357 }}
