It is a spectral type G star, about 1.16 solar masses and radii greater than our Sun, and only 200 kelvins hotter. It is estimated to be 2.6 billion years old.[1][2] Planetary systemOn October 9, 2007, a report was submitted to The Astrophysical Journal Letters telling of the discovery of an exoplanet transiting HAT-P-5. The planet was described as a Jupiter-like hot Jupiter, with a radius about one and one quarter times that of Jupiter, and nearly the same mass. Its density was reported as 0.66 ± 0.11 g/cm3, and its inclination 86.75 ± 0.44°. {{OrbitboxPlanet begin}}{{OrbitboxPlanet| exoplanet = b | mass = 1.06 ± 0.11 | period = 2.788491 ± 2.5e-05 | semimajor = 0.04075 ± 0.00076 | eccentricity = 0 }}{{Orbitbox end}} See also
