GJ 433 b
GJ 433 b
GJ 433 b is an exoplanet orbiting the star GJ 433, located about 29.8 light-years ( 9.1 pc) away from Solar System. Its discovery was publicly announced on 2009.
The host star GJ 433 has apparent magnitude of 9.8, with absolute magnitude of 10.0. It is 0.5 times more massive and 0.5 times bigger compared with our Sun. The surface temperature is 3600 with its spectral types of M1.5
In this planetary system, the extrasolar planet GJ 433 b orbits around the star GJ 433 every 7.4 days with its orbital distance of 0.06 AU ( 9275068.0 km)
(Projected orbit of GJ 433 b around its host star GJ 433)
