Kepler-109 b
Kepler-109 b
Kepler-109 b is an exoplanet orbiting the star Kepler-109, located about 1545.8 light-years (473.9 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star Kepler-109 has apparent magnitude of 12.4, with absolute magnitude of 4.0. It is 1.0 times more massive and 1.4 times bigger compared with our Sun. The surface temperature is 5917 with its spectral types of G1
In this planetary system, the extrasolar planet Kepler-109 b orbits around the star Kepler-109 every 6.5 days with its orbital distance of 0.07 AU ( 10311753.7 km)
