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.
Mercury is classified as a terrestrial planet. The gas giants are the other group.
Mercury is a terrestrial (rocky) planet. The four gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune.
Mercury is one of the four inner rocky planets, also know as terrestrial planets. The four Gas planets are the outer four; Jupiter, Saturn, Uranus and Neptune
Mercury is one of the four inner terrestrial planets, or rocky planets. It is the smallest of the four and closest to the sun. It is also the smallest of all eight planets.
Mercury is a terrestrial planet.

While Venus does have clouds of sulfuric acid it has a solid surface and in theory could be landed upon. In short it is a terrestrial planet.
No. Mars is a rocky planet, similar to earth in some ways. We are attempting at this very moment to determine if there was ever life on Mars, or if Mars could possibly sustain life in the future.
Mars is a terrestrial (rocky) planet, also known as an inner planet.
Saturn is not a terrestrial planet, so it is a gas planet.
In order from least to greatest in mean radius:Vesta (protoplanet)Pallas (protoplanet)Charon+ (dwarf planet)Orcus (dwarf planet)Quaoar (dwarf planet)Ceres (dwarf planet)Sedna (dwarf planet)"Snow White" [2007 OR10]* (dwarf planet)Haumea* (dwarf planet)Makemake (dwarf planet)Pluto+ (dwarf planet)Eris (dwarf planet)Mercury (terrestrial planet)Mars (terrestrial planet)Venus (terrestrial planet)Earth (terrestrial planet)Neptune (ice giant)Uranus (ice giant)Saturn (gas giant)Jupiter (gas giant)*There is a slight discrepancy as to how Haumea ought to be measured, due to its unusual shape. This makes it slightly unclear as to which is considered larger between Haumea and "Snow White."+Binary planet
It is a rocky planet or terrestrial planet. Any planet before Mars is terrestrial and any planet after Mars is a gas giant.
A terrestrial planet, Gas giant planets are made of gas....
Mars is a terrestrial planet, not a gas giant. Mars is a terrestrial planet because the majority of it is rock, not gas.
A terrestrial planet, Gas giant planets are made of gas....
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.
The opposite of terrestrial planet is gas giant
Mercury is a rocky planet, just like all the terrestrial planets: Mercury, Venus, Earth and Mars.
Jupiter is a gas giant planet.
it is a gas giant.
mars is a terrestrial planet or an inner planet
Haumea is a rocky, terrestrial dwarf planet.
While Venus does have clouds of sulfuric acid it has a solid surface and in theory could be landed upon. In short it is a terrestrial planet.
