K-type main sequence star in constellation Canes Venatici
HAT-P-12 is amagnitude 13 low-metallicityK dwarf star approximately 463light years away in theconstellation Canes Venatici , which hosts one known exoplanet.[ 3] [ 2]
The designationHAT-P-12 indicates that this was the 12th star found to have a planet by theHATNet Project .
In August 2022, this planetary system was included among 20 systems to be named by the thirdNameExoWorlds project.[ 7] Hungary , were announced in June 2023. HAT-P-12 is namedKomondor and its planet is namedPuli , after the HungarianKomondor andPuli dog breeds.[ 8]
In 2009 anexoplanet ,HAT-P-12b , was discovered by theHATNet Project orbiting this star. The planet was discovered using thetransit method and confirmed by follow upradial velocity measurements.[ 3] Transit-timing variations suggest the possible presence of additional non-transiting planets in the system.[ 9]
