kappa CrB b
kappa CrB b
kappa CrB b is an exoplanet orbiting the star kappa CrB, located about 99.5 light-years (30.5 pc) away from Solar System. Its discovery was publicly announced on 2007.
The host star kappa CrB has apparent magnitude of 4.8, with absolute magnitude of 2.4. It is 1.5 times more massive and 5.0 times bigger compared with our Sun. The surface temperature is 4960 with its spectral types of K1IVa
In this planetary system, the extrasolar planet kappa CrB b orbits around the star kappa CrB every 1251.0 days with its orbital distance of 2.60 AU ( 388954463.8 km)
