gamma Lib b
gamma Lib b
gamma Lib b is an exoplanet orbiting the star gamma Lib, located about 163.2 light-years (50.0 pc) away from Solar System. Its discovery was publicly announced on 2018.
The host star gamma Lib has apparent magnitude of 3.0, with absolute magnitude of -0.5. It is 1.5 times more massive and 11.1 times bigger compared with our Sun. The surface temperature is 4822 with its spectral types of K0III
In this planetary system, the extrasolar planet gamma Lib b orbits around the star gamma Lib every 415.2 days with its orbital distance of 1.24 AU ( 185456480.3 km)
(Projected orbit of gamma Lib b around its host star gamma Lib)
