HS Psc b
HS Psc b
HS Psc b is an exoplanet orbiting the star HS Psc, located about 122.9 light-years (37.7 pc) away from Solar System. Its discovery was publicly announced on 2024.
The host star HS Psc has apparent magnitude of 10.9, with absolute magnitude of 8.0. It is 0.7 times more massive and 0.7 times bigger compared with our Sun. The surface temperature is 4203 with its spectral types of KTV
In this planetary system, the extrasolar planet HS Psc b orbits around the star HS Psc every 4.0 days with its orbital distance of 0.04 AU ( 6507507.4 km)
(Projected orbit of HS Psc b around its host star HS Psc)
