Gases
No planet is made of glass, as far as I know. The giant planets - Jupiter, Saturn, Uranus, Neptune - are large, and made mostly of gas. However, they are not fast-moving.The inner planets - Mercury, Venus, Earth, Mars - are slow, fast-moving, and made basically of rock.
Neptune is a gas giant - or to be precise an ice giant.

The outer planets are mostly composed of gases and the inner planets are mostly made of rock, metals.

Rocks
They are mostly different kinds of gas.
Because they are mostly made out of gas and they are big or giant
Jupiter is mostly made of gases like methane and other gases like most outer giant planets
Jupiter is mostly made of gases like methane and other gases like most outer giant planets
The gas giant planets are composed mostly of hydrogen, methane, and ammonia.
