HAT-P-6b is an exoplanet discovered by the transit method and located at approximately 650 swl. in the direction of the Andromeda constellation, in orbit around the star HAT-P-6 . Belongs to the class of hot jupiters . The diameter in orbit is 7.832 gigameters, makes a revolution around the star in 92 hours, 28 minutes, 17 seconds. The true mass of this planet is 5.7% greater than the mass of Jupiter, and 33% in radius. Such indicators indicate a density of 0.45 g / cmΒ³, and this is less than that of water. The planet was discovered on October 15, 2007.
