HD 2952 b
HD 2952 b
HD 2952 b is an exoplanet orbiting the star HD 2952, located about 360.0 light-years (110.4 pc) away from Solar System. Its discovery was publicly announced on 2013.
The host star HD 2952 has apparent magnitude of 5.9, with absolute magnitude of 0.7. It is 2.5 times more massive and 12.0 times bigger compared with our Sun. The surface temperature is 4844 with its spectral types of K0III
In this planetary system, the extrasolar planet HD 2952 b orbits around the star HD 2952 every 311.6 days with its orbital distance of 1.20 AU ( 179517444.8 km)
