HD 169830

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. 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, and is predicted to come as close as 6.3561 pc in 2.08 million years. HD 169830 is known to be orbited by two large Jupiter-like exoplanets.

This is an F-type main-sequence star with a stellar classification of F7V. It is 3.83 billion years old and chromospherically inactive with a slow rotation rate, having a projected rotational velocity of 3.83 km/s. 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 times the luminosity of the Sun from its photosphere at an effective temperature of 6,300 K.

A candidate stellar companion, designated component B, lies at an angular separation of $0.517$ along a position angle of 265°.

Planetary system
On April 15, 2000, the Geneva Extrasolar Planet Search Team announced the discovery of a minimum mass planet in a 226-day orbit. Three years later on June 30, 2003, the same team, using the same method, discovered a minimum mass second planet orbiting the star. In 2022, the inclination and true mass of HD 169830 c were measured via astrometry.
