beta Cir b
beta Cir b
beta Cir b is an exoplanet orbiting the star beta Cir, located about 99.7 light-years (30.6 pc) away from Solar System. Its discovery was publicly announced on 2015.
The host star beta Cir has apparent magnitude of 22.0, with absolute magnitude of 19.6. It is 2.0 times more massive and 1.5 times bigger compared with our Sun. The surface temperature is 8676 with its spectral types of A3V
