Abstract • We report the discovery of a planet transiting a moderately bright (V=12.00) G star, with an orbital period of 2.788491+/-0.000025 days. From the transit light curve we determine that the radius of the planet is R_p=1.257+/-0.053 R_J. HAT-P-5b has a mass of M_p=1.06+/-0.11 M_J, similar to the average mass of previously known transiting exoplanets, and a density of ρ_p=0.66+/-0.11 g cm^-3. We find that the center of transit is T_c=2,454,241.77663+/-0.00022 days (HJD), and the total transit duration is 0.1217+/-0.0012 days.

Based in part on observations obtained with the SOPHIE spectrograph mounted on the 1.93 m telescope at the Haute Provance Observatory.
