gam Psc b
gam Psc b
gam Psc b is an exoplanet orbiting the star gam Psc, located about 134.8 light-years (41.3 pc) away from Solar System. Its discovery was publicly announced on 2021.
The host star gam Psc has apparent magnitude of 22.0, with absolute magnitude of 18.9. It is 1.0 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 5500 with its spectral types of G9 III
In this planetary system, the extrasolar planet gam Psc b orbits around the star gam Psc every 555.1 days with its orbital distance of 1.32 AU ( 197469189.3 km)
(Projected orbit of gam Psc b around its host star gam Psc)
