beta Umi b
beta Umi b
beta Umi b is an exoplanet orbiting the star beta Umi, located about 130.9 light-years (40.1 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star beta Umi has apparent magnitude of 2.1, with absolute magnitude of -0.9. It is 1.4 times more massive and 42.1 times bigger compared with our Sun. The surface temperature is 4126 with its spectral types of K4III
In this planetary system, the extrasolar planet beta Umi b orbits around the star beta Umi every 522.3 days with its orbital distance of 1.40 AU ( 209437019.0 km)
