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.
It is not small and rocky, it is a gas giant!
its a rocky planet
It's A Rock. A Gas you can't feel. I'm going to say that yes it is a rock but our second thought was gas so don't feel mistakened
Mercury is a rocky planet.It's actually a rock because it is one of the inner planets that are all made of rock.The planet Mercury is a dense, rocky, airless world.
Saturn is a gas giant, there is no solid surface.
It is a rocky planet or terrestrial planet. Any planet before Mars is terrestrial and any planet after Mars is a gas giant.
Mercury is a rocky planet, just like all the terrestrial planets: Mercury, Venus, Earth and Mars.
It is not small and rocky, it is a gas giant!
Mercury is a rocky planet and is too close to the sun to retain much of an atmosphere, much less become a gas giant.
Gas giant planet.
its a rocky planet
Earth is the largest rocky planet. After Earth is Venus, then Mars, and then the smallest, Mercury.
It is a gas giant planet.
Mercury is a rocky planet.
The name of the planet is "Uranus". It's a gas giant. * Mercury, Venus, Earth, Mars are rocky planets. * Jupiter, Saturn, Uranus, and Neptune are gas giants.
Saturn is a gas giant composed mainly of hydrogen and helium. It does not have a solid surface like rocky planets such as Earth or Mars.
Saturn is classified as a gas giant, consisting primarily of hydrogen and helium with a small rocky core at its center.
