HAT-P-11 b
HAT-P-11 b
HAT-P-11 b is an exoplanet orbiting the star HAT-P-11, located about 123.3 light-years (37.8 pc) away from Solar System. Its discovery was publicly announced on 2009.
The host star HAT-P-11 has apparent magnitude of 9.6, with absolute magnitude of 6.7. It is 0.8 times more massive and 0.8 times bigger compared with our Sun. The surface temperature is 4864 with its spectral types of K4
In this planetary system, the extrasolar planet HAT-P-11 b orbits around the star HAT-P-11 every 4.9 days with its orbital distance of 0.05 AU ( 7928687.1 km)
(Projected orbit of HAT-P-11 b around its host star HAT-P-11)
