Kepler-90 f
Kepler-90 f
Kepler-90 f is an exoplanet orbiting the star KOI-351, located about 2765.2 light-years (847.8 pc) away from Solar System. Its discovery was publicly announced on 2013.
The host star KOI-351 has apparent magnitude of 14.0, with absolute magnitude of 4.4. It is 1.2 times more massive and 1.2 times bigger compared with our Sun. The surface temperature is 6015 with its spectral types of G0
In this planetary system, the extrasolar planet Kepler-90 f orbits around the star KOI-351 every 124.9 days with its orbital distance of 0.48 AU ( 71806977.9 km)
