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.
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.
Saturn is not a terrestrial planet, so it is a gas planet.
Its a "Gas Giant". :) Saturn, Uranus and Neptune are also Gas Giants.
No. It is a gas giant. Terrestrial planets are planets that are mainly made of land.
Mercury and Venus are terrestrial planets, while Earth is also a terrestrial planet but with unique characteristics that support life. Mars is a terrestrial planet with a thin atmosphere. Jupiter, Saturn, Uranus, and Neptune are gas giants made mostly of hydrogen and helium.
It is a rocky planet or terrestrial planet. Any planet before Mars is terrestrial and any planet after Mars is a gas giant.
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.
Earth is a terrestrial planet, like Mercury, Venus, and Mars, that is composed primarily of rock and metal. Gas giants, on the other hand, are mostly made up of hydrogen and helium, like Jupiter and Saturn.
Mercury is a rocky planet, just like all the terrestrial planets: Mercury, Venus, Earth and Mars.
Jupiter is a gas giant planet.
Out of all the planets in our solar system, four are considered gas giants or Jovian planets. They are Saturn, Neptune, Uranus and Jupiter. The ones that are not gas giants are Mars, Mercury, Venus, and Earth.
mars is a terrestrial planet or an inner planet
The opposite of terrestrial planet is gas giant
Jupiter is one of the four gas giant planets, the outer planets.
Pluto is classified as a dwarf planet, not a terrestrial planet or a giant gas planet. It is primarily composed of rock and ice, similar to terrestrial planets like Earth, but it lacks the characteristics of a true terrestrial planet or a gas giant.
