HAT-P-5b is a transiting extrasolar planet located approximately 1000 light-years away in the constellation of Lyra, orbiting the star HAT-P-5. It is a hot Jupiter with a mass 6% greater than Jupiter and a radius 26% greater than Jupiter, corresponding to a density of 0.66 g/cm3, which is less than water. This planet was found by Bakos et al. on October 9, 2007.[3]
The planet HAT-P-5b is named Kráľomoc. The name was selected in the NameExoWorlds campaign by Slovakia, during the 100th anniversary of the IAU. Kráľomoc is an ancient Slovak term for the planet Jupiter.[4][5]
