DH Tau b
DH Tau b
DH Tau b is an exoplanet orbiting the star DH Tau, located about 435.2 light-years (133.4 pc) away from Solar System. Its discovery was publicly announced on 2005.
The host star DH Tau has apparent magnitude of 13.7, with absolute magnitude of 8.1. It is 0.4 times more massive and 0.4 times bigger compared with our Sun. The surface temperature is 3750 with its spectral types of M0.5V
