The term planet refers to celestial bodies orbiting a [[star]] with a [[gravity]] in a specific range. The gravity of a planet has to be strong enough to hold fluids in a stable state (hydrostatic equilibrium) which prevents them from escaping the planet and low enough to prevent nuclear processes to start as in stars. | The term planet refers to celestial bodies orbiting a [[star]] with a [[gravity]] in a specific range.
