GJ 849 b
GJ 849 b
GJ 849 b is an exoplanet orbiting the star GJ 849, located about 28.8 light-years ( 8.8 pc) away from Solar System. Its discovery was publicly announced on 2006.
The host star GJ 849 has apparent magnitude of 10.4, with absolute magnitude of 10.6. It is 0.5 times more massive and 0.5 times bigger compared with our Sun. The surface temperature is 3500 with its spectral types of M3.5V
In this planetary system, the extrasolar planet GJ 849 b orbits around the star GJ 849 every 1914.0 days with its orbital distance of 2.35 AU ( 351554996.1 km)
