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.
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]
