About this world

TrES-2 b is a gas giant orbiting TrES-2, a yellow, Sun-like star (type G0V) 702 light-years from Earth. It is about 1.4 times the size of Jupiter and holds 1.5 Jupiter masses. It completes an orbit every 2.47 days at 0.036 AU from its star, closer than Mercury is to the Sun.

Its equilibrium temperature is about 1,466 K (1,193 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium. Its atmosphere has already been studied: 8 spectroscopic observations.

It was discovered in 2006 by transit with TrES. A planet crosses its star and dims it by a tiny, periodic fraction.
