HR 810 b
HR 810 b
HR 810 b is an exoplanet orbiting the star HR 810, located about 56.0 light-years (17.2 pc) away from Solar System. Its discovery was publicly announced on 1999.
The host star HR 810 has apparent magnitude of 5.4, with absolute magnitude of 4.2. It is 1.1 times more massive and 1.9 times bigger compared with our Sun. The surface temperature is 5997 with its spectral types of G0V pecul.
In this planetary system, the extrasolar planet HR 810 b orbits around the star HR 810 every 320.1 days with its orbital distance of 0.93 AU ( 138378030.4 km)
