About this world
CoRoT-3 b is a gas giant orbiting CoRoT-3, a yellow-white F-type star (type F3V) 2.51 thousand light-years from Earth. It is about 1 times the size of Jupiter and holds 22 Jupiter masses. It completes an orbit every 4.26 days at 0.058 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,695 K (1,422 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2008 by transit with CoRoT. A planet crosses its star and dims it by a tiny, periodic fraction.
