AF Lep b
AF Lep b
AF Lep b is an exoplanet orbiting the star AF Lep, located about 87.6 light-years (26.8 pc) away from Solar System. Its discovery was publicly announced on 2023.
The host star AF Lep has apparent magnitude of 6.3, with absolute magnitude of 4.2. It is 1.2 times more massive and 1.2 times bigger compared with our Sun. The surface temperature is 6130 with its spectral types of F8V
In this planetary system, the extrasolar planet AF Lep b orbits around the star AF Lep every 8145.0 days with its orbital distance of 8.20 AU ( 1226702539.7 km)
