HAT-P-67
HAT-P-67 is a binary star system, made up of a F-type subgiant and a red dwarf star, which is located about 1,200 light-years away in the constellation Hercules. There is a hot Saturn planet orbiting the primary star, which is named HAT-P-67b.
The stellar system consists of the F class primary star with a red dwarf companion separated by 9 arc-seconds or about 3400 astronomical units. According to measurements taken by the Gaia spacecraft the two stars have nearly identical parallax and proper motions confirming that they are a binary system.
The primary star is a rapidly rotating subgiant star with a radius 2.65 times that of the Sun and a mass 1.64 times that of the Sun.
The secondary star is a red dwarf with a radius 0.68 times that of the Sun and a mass 0.58 times that of the Sun.
There is one known planet orbiting HAT-P-67A. HAT-P-67b is a gas giant planet transiting its parent star every 4.8 days, at an orbital distance of 0.065 astronomical units (9,700,000 km). It is one of the largest and lowest density planets known as of 2024[update].
