Mercury, Venus, Earth and Mars are all rock planets. The more technical term is terrestrial planets and they are composed of almost entirely of rock and metal. Each has a tiny amount of atmospheric gas and Earth has a tiny amount of liquid water.
The other four planets are the gas giant planets, Jupiter, Saturn, Uranus and Neptune. That means they do not have a solid surface that is visible and much of the mass of the planet is the gaseous material. (All must have some small inner region consisting of rocky material, even if it is a tiny fraction of the mass that has been collected from stray asteroids.)
The two gas giants closest to the Sun, Jupiter and Saturn, are the two largest in the solar system with Jupiter the largest of all. Both are composed mainly of hydrogen and helium.
The outermost gas giants are called ice giants. Being colder, Uranus and Neptune have formed with substantial quantities of water, ammonium and methane with smaller amounts of hydrogen and helium in the outer regions. The water, ammonium and methane are solid at these temperatures, so the center of these planets is primarily frozen gasses with hydrogen and helium being predominant as an atmosphere.
What else can I help you with?
Does mercury have any gases?
Mercury has a thin atmosphere that is made up of many gases, including: hydrogen, helium, oxygen, calcium, potassium, sodium and water vapor. Mercury is the smallest planet.
Is a terrestrial planet Mercury or Jupiter?
It's a "terrestrial" planet, because it is rocky with an iron core, like planet Earth. "Terrestrial" means "Earthlike". Jovian planets are mainly made of gases and liquefied gases.
How old was planet Mercury when it was made?
Planet Mercury was zero years of age when it was made.
What plant is mostly made of gases Mercury Mars Venus or Jupiter?
Jupiter is the planet mostly made of gases. It is a gas giant, primarily composed of hydrogen and helium, with no solid surface like terrestrial planets. In contrast, Mercury, Mars, and Venus are rocky planets with solid surfaces.
What made the tracks on the planet mercury?
what made the tracks on planet mercury is rover, the space robot, who was sent from the nasa space station to look for any sign of human life on planet mercury.
How pollution take place?
Man-made non-natural solids, liquids, or gases are left on our planet.

Is Mercury large and made mostly of gases?
No its a small planet. It has a radius of 2439 km or 1515 miles. Its not made of gas...its a rocky planet made of mostly iron. Planets that do fit your description are Jupiter, Saturn, Neptune and Uranus.
