CoRoT-21 b
CoRoT-21 b
CoRoT-21 b is an exoplanet orbiting the star CoRoT-21, located about 4562.9 light-years (1399.0 pc) away from Solar System. Its discovery was publicly announced on 2011.
The host star CoRoT-21 has apparent magnitude of 16.0, with absolute magnitude of 5.3. It is 1.3 times more massive and 1.9 times bigger compared with our Sun. The surface temperature is 6200 with its spectral types of F8IV
In this planetary system, the extrasolar planet CoRoT-21 b orbits around the star CoRoT-21 every 2.7 days with its orbital distance of 0.04 AU ( 6238231.2 km)
