HAT-P-13c is on the very upper end of the super-Jupiters and lower end of the brown dwarf range, being 15.2 times as massive as Jupiter. It possibly could be a brown dwarf star instead of a supergiant planet. It orbits around its star, HAT-P-13, every 428.5 days, and it's 698 light years away from Earth.[1][2][3] It is part of a multiple-body system containing also "the first transiting planet (HAT-P-13b) that is accompanied by a well-characterized longer-period companion planet (HAT-P-13c)."[4]
