我们报告发现一颗行星凌日一颗中等亮度（V = 12.00）的G恒星，其轨道周期为2.788491±0.000025天。通过凌日光曲线，我们确定了行星的半径Rp = 1.257±0.053 RJ。HAT-P-5b的质量为Mp = 1.06±0.11 MJ，与之前已知的凌日系外行星的平均质量相似，密度为ρp = 0.66±0.11 g cm−3。我们发现凌日中心Tc = 2,454,241.77663±0.00022天（HJD），总凌日时间为0.1217±0.0012天。
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 Rp = 1.257 ± 0.053 RJ. HAT-P-5b has a mass of Mp = 1.06 ± 0.11 MJ, similar to the average mass of previously known transiting exoplanets, and a density of ρp = 0.66 ± 0.11 g cm −3. We find that the center of transit is Tc = 2,454,241.77663 ± 0.00022 days (HJD), and the total transit duration is 0.1217 ± 0.0012 days.
