CoRoT-31 b
CoRoT-31 b
CoRoT-31 b is an exoplanet orbiting the star CoRoT-31, located about 7142.8 light-years (2190.0 pc) away from Solar System. Its discovery was publicly announced on 2017.
The host star CoRoT-31 has apparent magnitude of 15.7, with absolute magnitude of 4.0. It is 1.2 times more massive and 2.1 times bigger compared with our Sun. The surface temperature is 5370 with its spectral types of G2IV
In this planetary system, the extrasolar planet CoRoT-31 b orbits around the star CoRoT-31 every 4.6 days with its orbital distance of 0.06 AU ( 8766435.2 km)
