chi Vir b
chi Vir b
chi Vir b is an exoplanet orbiting the star chi Vir, located about 293.5 light-years (90.0 pc) away from Solar System. Its discovery was publicly announced on 2009.
The host star chi Vir has apparent magnitude of 4.7, with absolute magnitude of -0.1. It is 2.2 times more massive and 20.9 times bigger compared with our Sun. The surface temperature is 4445 with its spectral types of K2III
In this planetary system, the extrasolar planet chi Vir b orbits around the star chi Vir every 835.5 days with its orbital distance of 2.14 AU ( 320139443.3 km)
