None. By definition a rocky planet is mostly rock. Venus, by far, has the densest atmosphere of the terrestrial planets, but the planet itself is mostly rock and is similar in composition to Earth.
Mars and Venus, I guess you could call them our sisters gone wrong.
Stars are primarily made of hydrogen and helium gas, while planets are composed of various elements such as rock, metal, and gas depending on their composition and location in the solar system.
Any atmosphere by definition is made of gas.
No, those are the outer planets.
venus and earth.
The four outer gas giants.
Jupiter and Saturn are mostly made of atmosphere, with Jupiter's atmosphere consisting mostly of hydrogen and helium, while Saturn's atmosphere is also primarily composed of hydrogen and helium, with traces of other elements.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.

Planets made mostly of gas are called gas giants. These planets have a thick atmosphere composed primarily of hydrogen and helium, with a small solid core at their center. Examples include Jupiter and Saturn in our solar system.
Earth and the other planets are mostly made of rock.
the earth is one
This one...the earth. The other planets are made up of critical gases,like methane, with frozen planets like Pluto made up of layers of frozen gases, such as a suspected layer of oxygen underneath layers of nitrogen and methane, and sulfuric gases which tend to snow out on the cold side of the planet.
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
