Kepler-297 c
Kepler-297 c
Kepler-297 c is an exoplanet orbiting the star Kepler-297, located about 2256.5 light-years (691.9 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star Kepler-297 has apparent magnitude of 13.1, with absolute magnitude of 3.9.
In this planetary system, the extrasolar planet Kepler-297 c orbits around the star Kepler-297 every 74.9 days with its orbital distance of 0.34 AU ( 50264884.6 km)
(Projected orbit of Kepler-297 c around its host star Kepler-297)
