HD 151613

HD 151613 is a binary star system in the northern circumpolar constellation of Draco. It is visible to the naked eye with an apparent visual magnitude of 4.84. The distance to this star, as estimated from its annual parallax shift of $0.375$, is 83 light years. It is moving closer to the Earth with a heliocentric radial velocity of −2 km/s.

This is a single-lined spectroscopic binary system with an orbital period of 363.57 days and an eccentricity of 0.35. The pair were resolved through speckle interferometry in 1977, showing an angular separation of $47.5$. They were later resolved in 1981 with a separation of $39.3 mas$, but were unresolved during 20 other attempts between 1976–1991. The system is a source of X-ray emission. The visible component is an F-type main-sequence star with a stellar classification of F2 V. It is around 2.3 billion years old with a projected rotational velocity of 48 km/s.
