HAT-P-6b is a transiting extrasolar planet[4] located approximately 650 light-years away in the constellation of Andromeda, orbiting the star HAT-P-6. This hot Jupiter planet orbits with a semi-major axis of about 7.832 gigameters, and takes 92 hours, 28 minutes, 17 seconds and 9 deciseconds to orbit the star. It has true mass of 5.7% greater than Jupiter and a radius 33% greater than Jupiter, corresponding to a density of 0.45 g/cm3, which is less than water. This planet was found by Noyes et al. on October 15, 2007.
