16 Lyrae is a suspected astrometric binary star system in the constellation Lyra, located 126 light years away from the Sun based on parallax. It is visible to the naked eye as a dim, white-hued star with a combined apparent visual magnitude of 5.00. The system is moving further away from the Earth with a heliocentric radial velocity of +5 km/s. It is a suspected member of the Ursa Major Moving Group stream. Cowley et al. (1969) found a stellar classification of A7 V for the visible component, matching an A-type main-sequence star that is generating energy through hydrogen fusion at its core. Abt and Morrell (1995) instead listed a class of A6 IV, suggesting it has left the main sequence and become a subgiant star. It is 791 million years old with a high rate of spin, showing a projected rotational velocity of 124 km/s. This system is a source for X-ray emission with a luminosity of 10,530,000,000,000,000,000,000 W, which is most likely coming from the unseen companion.
