HAT-P-20 is a K-type main-sequence star about 232 light-years away. The star has a strong starspot activity, and its equatorial plane is misaligned by 36° with the planetary orbit. Although star with a giant planet on close orbit is expected to be spun-up by tidal forces, only weak indications of tidal spin-up were detected. Planetary system In 2010 a transiting hot super-Jovian planet was detected. Its equilibrium temperature is 996 K.
