HAT-P-28 b
HAT-P-28 b
HAT-P-28 b is an exoplanet orbiting the star HAT-P-28, located about 1288.3 light-years (395.0 pc) away from Solar System. Its discovery was publicly announced on 2011.
The host star HAT-P-28 has apparent magnitude of 13.0, with absolute magnitude of 5.0. It is 1.0 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 5680 with its spectral types of G3
In this planetary system, the extrasolar planet HAT-P-28 b orbits around the star HAT-P-28 every 3.3 days with its orbital distance of 0.04 AU ( 6492547.6 km)
