they are made mostly of gas except for pluto which is mostly ice
The four outer gas giants.
All of the planets in the solar system have at least some trace gases in their atmospheres, but the planets known as gas giants are composed of mostly gases. They are the four outermost planets, Jupiter, Saturn, Neptune, and Uranus. In contrast, the four innermost planets, Mercury, Venus, Earth, and Mars, are called the terrestrial planets and are mostly composed of solids.
Yes, the first four planets in our solar system are rocky planets. They are Mercury, Venus, Earth, and Mars. These planets have solid surfaces made mostly of rock and metal.
There are four planets that are made out of gas: Jupiter, Saturn, Urans and Neptune. These planets are called the "gas giants" . The other four planets (Earth, Mercury, Venus and Mars) are mostly made out of rock.
Well, if you take all the planets together, taking into account that Jupiter and Saturn are enormous and consist mostly of hydrogen and helium gasses, then you'd have to say that the planets are made mostly of hydrogen and helium gas. But if you are allowed to give separate answers for the different planets, you'd say that the four terrestrial planets are made mostly out of silicate (rocky) material with a core of nickel-iron alloy, that Jupiter and Saturn are made mostly of a mixture of hydrogen and helium gasses, and that Urnaus and Neptune are made mostly of hydrogen and helium gases with substantial cores of water ice.
Ices.

Earth and the other planets are mostly made of rock.
because they are made of mostly metal and rock while the bigger planets are mostly made of gas
The first four inner planets (Mercury, Venus, Earth, Mars) are mostly made of rock and metal. They have solid surfaces and are composed of materials like silicate minerals, metals such as iron and nickel, and smaller amounts of other elements.
Well, if you take all the planets together, taking into account that Jupiter and Saturn are enormous and consist mostly of hydrogen and helium gasses, then you'd have to say that the planets are made mostly of hydrogen and helium gas. But if you are allowed to give separate answers for the different planets, you'd say that the four terrestrial planets are made mostly out of silicate (rocky) material with a core of nickel-iron alloy, that Jupiter and Saturn are made mostly of a mixture of hydrogen and helium gasses, and that Urnaus and Neptune are made mostly of hydrogen and helium gases with substantial cores of water ice.
The four inner planets are smaller than the four outer planets. The inner planets are made up mostly of iron and various types of rock. The outer planets are mostly hydrogen, helium, and ice. The inner planets each completely rotate in less than an earth day. The inner planets all rotate faster than the outer planets.
No, those are the outer planets.
They are made mostly of hydrogen and helium.
