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]
