24 Sex c
24 Sex c
24 Sex c is an exoplanet orbiting the star 24 Sex, located about 252.6 light-years (77.5 pc) away from Solar System. Its discovery was publicly announced on 2010.
The host star 24 Sex has apparent magnitude of 7.4, with absolute magnitude of 2.9. It is 1.5 times more massive and 4.9 times bigger compared with our Sun. The surface temperature is 5098 with its spectral types of G5
In this planetary system, the extrasolar planet 24 Sex c orbits around the star 24 Sex every 883.0 days with its orbital distance of 2.08 AU ( 311163571.1 km)
(Projected orbit of 24 Sex c around its host star 24 Sex)
The Star 24 Sex 's habitable zone is located at the following distance
