PPL 15 b
PPL 15 b
PPL 15 b is an exoplanet orbiting the star PPL 15, located about 463.1 light-years (142.0 pc) away from Solar System. Its discovery was publicly announced on 1999.
The host star PPL 15 has apparent magnitude of 20.0, with absolute magnitude of 14.2. It is 0.1 times more massive and 0.1 times bigger compared with our Sun. The surface temperature is 3100 with its spectral types of M6.5
In this planetary system, the extrasolar planet PPL 15 b orbits around the star PPL 15 every 5.8 days with its orbital distance of 0.02 AU ( 2991957.4 km)
(Projected orbit of PPL 15 b around its host star PPL 15)
