HAT-P-3, also known as Dombay and TOI-1419, is a binary star system consisting of a K-type main-sequence star and a red dwarf about 440.6 light-years away in the constellation Ursa Major. A single Jovian planet orbits so close to the system's primary star that its year lasts for only 2.9 Earth-days
