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 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 our Sun. Combining the mass and radius makes the surface gravity only 41% that of our 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 along a position angle of 265°. Planetary system. On April 15, 2000, the Geneva  Extrasolar Planet Search Team announced the discovery of a 3 M planet in a 226-day orbit. Three years later on June 30, 2003, the same team, using the same method, discovered a 3.5 M second planet orbiting the star.
