HAT-P-25 is a G-type main-sequence star about 985 light-years away. It has a very low flare activity.[4] The star is enriched in heavy elements, having about twice amount of metals compared to solar abundance.

Planetary system

In 2010 a transiting hot Jupiter like planet was detected.[5] It has an equilibrium temperature of 1182±25 K.[3] The stability of orbits within circumstellar habitable zone is not significantly affected by the HAT-P-25b planet.[6]
