GW Lib b
GW Lib b
GW Lib b is an exoplanet orbiting the star GW Lib, located about 326.2 light-years (100.0 pc) away from Solar System. Its discovery was publicly announced on 2010.
The host star GW Lib has apparent magnitude of 16.2, with absolute magnitude of 11.2. It is 0.8 times more massive compared with our Sun. The surface temperature is 14700 with its spectral types of DA
In this planetary system, the extrasolar planet GW Lib b orbits around the star GW Lib every 0.1 days with its orbital distance of 0.00 AU ( 398977.5 km)
