HD 169830
Star in the constellation Sagittarius
HD 169830 is a star in the southern constellation of Sagittarius. It has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.90.[2] The star is located at a distance of 120 light years from the Sun based on parallax. It is drifting closer with a radial velocity of −17.3 km/s,[4] and is predicted to come as close as 20.7 ly (6.4 pc) in 2.08 million years.[10] HD 169830 is known to be orbited by two large Jupiter-like exoplanets.
This is an F-type main-sequence star[6] with a stellar classification of F7V.[3] It is 3.83[8] billion years old and chromospherically inactive[8] with a slow rotation rate,[8] having a projected rotational velocity of 3.83 km/s.[5] This star is 40% more massive and 84% larger than the Sun. Combining the mass and radius makes the surface gravity only 41% that of the Sun. It is radiating 4.6[6] times the luminosity of the Sun from its photosphere at an effective temperature of 6,300 K.[6]
A candidate stellar companion, designated component B, lies at an angular separation of 11″ along a position angle of 265°.[11]
