47 Ursae Majoris system. Artwork of sunrise on a moon of a ringed gas giant planet in the 47 Ursae Majoris (47 UMa) system. 47 UMa (lower right) is a nearby Sun-like star. Its two gas giant planets would orbit between Mars and Jupiter if placed in our solar system. The second planet, 47 UMa b, was discovered in 1995 and its mass is 2.5 Jupiters. 47 UMa c was detected in 2001 and has a mass of 0.75 Jupiters. Unlike most such planets found, both of these have circular orbits outside their star's habitable zone. This habitable zone could contain an as yet undetected Earth-like world.
