Is Mercury a gassy planet

Answer 1

Mercury is a rock planet; it is solid. Any planet to the left of the asteroid belt (Mercury, Venus, Earth and Mars) are rock planets, or terrestrial planets, while any planet to the right of the asteroid belt are gaseous (Jupiter, Saturn, Neptune, Uranus).

Answer 2

Pluto is neither gassy like the gas giants, nor categorized as a planet anymore. The surface does have frozen nitrogen, methane, and carbon dioxide believed to cover a deep layer of water ice around a rocky core.

Answer 3

No, Mercury is not a gassy planet. It is mostly composed of rock and metal, with a very thin atmosphere primarily made up of oxygen, sodium, hydrogen, helium, and potassium. Its atmosphere is too thin to be considered gassy like the gas giants in our solar system.
