description 47 Ursae Majoris Overview
47 Ursae Majoris is a yellow G-type main-sequence star located approximately 46 light-years away from Earth in the constellation of Ursa Major. It is notable for its close physical resemblance to the Sun and for hosting a multi-planet planetary system, a rarity among early exoplanet discoveries. The star's system includes three confirmed Jupiter-mass gas giants orbiting in nearly circular paths, the first of which was detected by astronomers in 1996.
