rho CrB b
rho CrB b
rho CrB b is an exoplanet orbiting the star rho CrB, located about 56.8 light-years (17.4 pc) away from Solar System. Its discovery was publicly announced on 1997.
The host star rho CrB has apparent magnitude of 5.4, with absolute magnitude of 4.2. It is 1.0 times more massive and 1.3 times bigger compared with our Sun. The surface temperature is 5822 with its spectral types of G0V or G2V
In this planetary system, the extrasolar planet rho CrB b orbits around the star rho CrB every 39.8 days with its orbital distance of 0.22 AU ( 33584722.0 km)
