Fomalhaut b
Fomalhaut b
Fomalhaut b is an exoplanet orbiting the star Fomalhaut, located about 25.1 light-years ( 7.7 pc) away from Solar System. Its discovery was publicly announced on 2008.
The host star Fomalhaut has apparent magnitude of 1.2, with absolute magnitude of 1.7. It is 1.9 times more massive and 1.8 times bigger compared with our Sun. The surface temperature is 8590 with its spectral types of A3 V
In this planetary system, the extrasolar planet Fomalhaut b orbits around the star Fomalhaut every 320000.0 days with its orbital distance of 117.00 AU ( 17502950871.9 km)
