CoRoT-20 b
CoRoT-20 b
CoRoT-20 b is an exoplanet orbiting the star CoRoT-20, located about 4011.7 light-years (1230.0 pc) away from Solar System. Its discovery was publicly announced on 2011.
The host star CoRoT-20 has apparent magnitude of 14.7, with absolute magnitude of 4.2. It is 1.1 times more massive and 0.9 times bigger compared with our Sun. The surface temperature is 5880 with its spectral types of G2V
In this planetary system, the extrasolar planet CoRoT-20 b orbits around the star CoRoT-20 every 9.2 days with its orbital distance of 0.09 AU ( 13493727.9 km)
