GJ 96 b
GJ 96 b
GJ 96 b is an exoplanet orbiting the star GJ 96, located about 38.9 light-years (11.9 pc) away from Solar System. Its discovery was publicly announced on 2018.
The host star GJ 96 has apparent magnitude of 9.3, with absolute magnitude of 9.0. It is 0.6 times more massive and 0.5 times bigger compared with our Sun. The surface temperature is 3785 with its spectral types of M0V
In this planetary system, the extrasolar planet GJ 96 b orbits around the star GJ 96 every 73.9 days with its orbital distance of 0.29 AU ( 43532980.4 km)
