47 Uma b
47 Uma b
47 Uma b is an exoplanet orbiting the star 47 Uma, located about 45.9 light-years (14.1 pc) away from Solar System. Its discovery was publicly announced on 1996.
The host star 47 Uma has apparent magnitude of 5.1, with absolute magnitude of 4.4. It is 1.0 times more massive and 1.2 times bigger compared with our Sun. The surface temperature is 5892 with its spectral types of G0V
In this planetary system, the extrasolar planet 47 Uma b orbits around the star 47 Uma every 1078.0 days with its orbital distance of 2.10 AU ( 314155528.5 km)
(Projected orbit of 47 Uma b around its host star 47 Uma)
