Kepler-436 b
Kepler-436 b
Kepler-436 b is an exoplanet orbiting the star Kepler-436, located about 1921.8 light-years (589.2 pc) away from Solar System. Its discovery was publicly announced on 2015.
The host star Kepler-436 has apparent magnitude of 16.3, with absolute magnitude of 7.4. It is 0.7 times more massive and 0.7 times bigger compared with our Sun. The surface temperature is 4734 with its spectral types of K4
In this planetary system, the extrasolar planet Kepler-436 b orbits around the star Kepler-436 every 64.0 days with its orbital distance of 0.34 AU ( 50713678.2 km)
(Projected orbit of Kepler-436 b around its host star Kepler-436)
