It has an apparent visual magnitude of 5.08,[2] which means it is a 5th magnitude star that is faintly visible to the naked eye. The system is located at a distance of 68\u00a0light years from the Sun based on parallax, and it is drifting closer with a radial velocity of \u221211\u00a0km\/s.[1] It is a candidate member of the Ursa Major Moving Group.[7]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4This is an ordinary F-type main-sequence star with a stellar classification of F7V,[3] indicating that the star is hotter and more massive than the Sun, giving it a yellow-white hue. The star is about two[5]\u00a0billion years old and is chromospherically quiet,[8] with a projected rotational velocity of 14.3\u00a0km\/s. It has about 1.5[1] times the radius and 1.3[5] times the mass of the Sun. The star is radiating 3.4 times the luminosity of the Sun from its photosphere at an effective temperature of 6,396\u00a0K.[5]Table of ContentsPlanetary system[edit]See also[edit]References[edit]External links[edit]Planetary system[edit]In September 2005, a massive planet was found on an eccentric orbit about the star, based on radial velocity variations measured by the ELODIE spectrograph. An infrared excess had been detected at a wavelength of 60\u00a0\u03bcm, suggesting the star may host a circumstellar disk. However, the existence of a disk is unlikely because the infrared radiation is coming from a background galaxy.[8]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4See also[edit]References[edit]^ a b c d e f g h i j k Brown, A.
