Kepler-244 b
Kepler-244 b
Kepler-244 b is an exoplanet orbiting the star Kepler-244, located about 3385.8 light-years (1038.1 pc) away from Solar System. Its discovery was publicly announced on 2014.
The host star Kepler-244 has apparent magnitude of 14.3, with absolute magnitude of 4.2.
In this planetary system, the extrasolar planet Kepler-244 b orbits around the star Kepler-244 every 4.3 days with its orbital distance of 0.05 AU ( 7479893.5 km)
(Projected orbit of Kepler-244 b around its host star Kepler-244)
