The team also suggests that, if its orbit is not exactly circular, Corot-7b is a hotbed of volcanic activity. [8], Kelvin–Helmholtz heating can cause a gas giant to radiate more energy than it receives from its host star. In the outer Solar System, hydrogen and helium are referred to as "gases"; water, methane, and ammonia as "ices"; and silicates and metals as "rock". It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form. Which of the gas giant planets is the smallest of the gas giants? Because Uranus and Neptune are primarily composed of, in this terminology, ices, not gas, they are increasingly referred to as ice giants and separated from the gas giants.
