Kepler-51 d
Kepler-51 d
Kepler-51 d is an exoplanet orbiting the star Kepler-51, located about 2555.8 light-years (783.6 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star Kepler-51 has apparent magnitude of 15.0, with absolute magnitude of 5.5. It is 1.0 times more massive and 0.8 times bigger compared with our Sun. The surface temperature is 5674 with its spectral types of G0
In this planetary system, the extrasolar planet Kepler-51 d orbits around the star Kepler-51 every 130.2 days with its orbital distance of 0.51 AU ( 76145316.2 km)
(Projected orbit of Kepler-51 d around its host star Kepler-51)
