HAT-P-12b, formally named Puli, is an extrasolar planet approximately 468 light years away from Earth, orbiting the 13th magnitude K-type star HAT-P-12, which is located in Canes Venatici constellation. It is a transiting hot Jupiter that was discovered by the HATNet Project on April 29, 2009.
HAT-P-12b is a H/He-dominated gas giant planet with a core mass of 11.3 M and is moderately irradiated by its low-metallicity host star. Therefore, HAT-P-12b is most likely an H/He-dominated planet with a core of perhaps ~10 M, and a total metal fraction of ~15%. This makes HAT-P-12b the least massive H/He-dominated gas giant planet found to date; the previous record holder was Saturn.
