Star
This star is classified as spectral type F7V, meaning the color of the photosphere of this star is yellow-white. It takes 9.5 days for the star to rotate once around its axis. 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.
Planetary system
On April 15, 2000, the Geneva Extrasolar Planet Search Team announced the discovery of a 3 MJ planet in a 226-day orbit. Three years later on June 30, 2003, the same two teams using the same method discovered a 3.5 MJ second planet orbiting about halfway between the distances of Mars and Jupiter (or in the middle of the asteroid belt) in the solar system from the star.
