We report the discovery of a new transiting extrasolar planet, HAT-P-55b. The planet orbits a V = 13.207 ± 0:039 sun-like star with a mass of 1.013 ± 0.037 M, a radius of 1:011 ± 0.036 R, and a metallicity of 0.03 ± 0:08. The planet itself is a typical hot Jupiter with a period of 3.5852467 ± 0.0000064 days, a mass of 0.582 ± 0.056 MJ and a radius of 1.182 ± 0.055 RJ. This discovery adds to the increasing sample of transiting planets with measured bulk densities, which is needed to put constraints on models of planetary structure and formation theories.
