GJ 758 b
GJ 758 b
GJ 758 b is an exoplanet orbiting the star GJ 758, located about 50.6 light-years (15.5 pc) away from Solar System. Its discovery was publicly announced on 2009.
The host star GJ 758 has apparent magnitude of 6.4, with absolute magnitude of 5.4. It is 1.0 times more massive and 0.9 times bigger compared with our Sun. The surface temperature is 5425 with its spectral types of K0V
In this planetary system, the extrasolar planet GJ 758 b orbits around the star GJ 758 every 109000.0 days with its orbital distance of 33.00 AU ( 4936729733.1 km)
(Projected orbit of GJ 758 b around its host star GJ 758)
