4 Ursae Majoris, also known as Pi² Ursae Majoris (π² UMa / π² Ursae Majoris) or traditionally named Muscida, is an orange giant star approximately 252 light-years away in the constellation of Ursa Major. As of 2007, an extrasolar planet has been confirmed to be orbiting the star.

Planetary system

The planet (named 4 Ursae Majoris b) is seven times more massive than Jupiter. Its orbit is eccentric, orbiting 4 Ursae Majoris at 87% the distance from Sun to Earth.
