- TrES-4b abstract "TrES-4b is an extrasolar planet at star GSC 02620-00648 in Hercules (constellation), as the second-largest planet ever found (if CT Chamaeleontis b was confirmed as a planet, it'd be second-largest, but if it's really a brown dwarf, then it's the largest), and it was discovered in 2006, announced in 2007, by the Trans-Atlantic Exoplanet Survey using the transit method. It is 1,430 light-years (440 pc) away in the constellation Hercules.TrES-4 orbits its primary star, GSC 02620-00648, every 3.543 days and eclipses it when viewed from Earth. The planet is 0.919 times as massive as Jupiter but 1.799 times the diameter, the largest planet ever found at the time (next to WASP-17b, found on 1 May 2009), giving it an average density of only about 0.333 grams per cubic centimetre. This made TrES-4 both the largest known planet and the planet with the lowest known density at the time of its discovery. TrES-4's orbital radius is 0.05091 AU, giving it a predicted surface temperature of about 1782 K. This by itself is not enough to explain the planet's low density, however. It is not currently known why TrES-4 is so large. The probable causes are the proximity to a parent star that is 3–4 times more luminous than the Sun as well as the internal heat within the planet.A 2008 study concluded that the GSC 06200-00648 system (among others) is a binary star system allowing even more accurate determination of stellar and planetary parameters.".
