    A massive planet. They are most commonly composed primarily of 'gas' (hydrogen and helium) or 'ices' (volatiles such as water, methane, and ammonia), but may also be composed primarily of rock, which would make one a Mega Earth. [3] Regardless of their bulk compositions, giant planets normally have thick atmospheres of hydrogen and helium. Jupiter
