QZ Lib b
QZ Lib b
QZ Lib b is an exoplanet orbiting the star QZ Lib, located about 610.6 light-years (187.2 pc) away from Solar System. Its discovery was publicly announced on 2018.
The host star QZ Lib has apparent magnitude of 22.0, with absolute magnitude of 15.6. It is 0.8 times more massive compared with our Sun. The surface temperature is 10500 with its spectral types of WD
In this planetary system, the extrasolar planet QZ Lib b orbits around the star QZ Lib every 0.1 days with its orbital distance of 0.00 AU ( 436669.1 km)
(Projected orbit of QZ Lib b around its host star QZ Lib)
