HD 199942

HD 199942 is a binary star system in the northern constellation of Equuleus. It is faintly visible to the naked eye with an apparent visual magnitude of 5.98. The system is located at a distance of approximately 184 light years based on parallax, and it has an absolute magnitude of 1.59. It is drifting closer with a radial velocity of −26 km/s.
This system is moving through the galaxy at a velocity of relative to the Sun. Its galactic orbit carry it somewhere between 25100-22000 light years from the galactic core, and it will come at its closest to the Sun 2.1 million years from now, at a distance of.
The binary nature of this system was discovered in 1934 by G. P. Kuiper, who found the pair had an angular separation of. The pair orbit each other with a period of 58.4 years and an eccentricity of 0.295. The primary component is of visual magnitude 6.23 and is a chemically-peculiar F-type main-sequence star with a class of F1Vp. The companion is of magnitude 8.13.
