GPX-1 b
GPX-1 b
GPX-1 b is an exoplanet orbiting the star GPX-1, located about 2136.0 light-years (654.9 pc) away from Solar System. Its discovery was publicly announced on 2020.
The host star GPX-1 has apparent magnitude of 11.3, with absolute magnitude of 2.2. It is 1.7 times more massive and 1.6 times bigger compared with our Sun. The surface temperature is 7000 with its spectral types of F2
In this planetary system, the extrasolar planet GPX-1 b orbits around the star GPX-1 every 1.7 days with its orbital distance of 0.03 AU ( 5056408.0 km)
(Projected orbit of GPX-1 b around its host star GPX-1)
