==Uranus and Neptune==

 

The upper mass limit of a gas giant planet is approximately 70 times that of Jupiter (around 0.08 times the mass of the [[Sun]]). Above this point, the intense heat and pressure at the planet's core begin to induce [[nuclear fusion]] and the planet ignites to become a [[red dwarf]]. Interestingly there appears to be a mass gap between the heaviest gas giant planets detected (about 10 times the mass of Jupiter) and the lightest red dwarfs. This has led to suggestions that the formation process for planets and [[binary star|binary stars]] may be fundamentally different.
