CoRoT-4 b
CoRoT-4 b
CoRoT-4 b is an exoplanet orbiting the star CoRoT-4, located about 2394.2 light-years (734.1 pc) away from Solar System. Its discovery was publicly announced on 2008.
The host star CoRoT-4 has apparent magnitude of 13.7, with absolute magnitude of 4.4. It is 1.1 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 6190 with its spectral types of F8V
In this planetary system, the extrasolar planet CoRoT-4 b orbits around the star CoRoT-4 every 9.2 days with its orbital distance of 0.09 AU ( 13463808.4 km)
(Projected orbit of CoRoT-4 b around its host star CoRoT-4)
