Nitrogen, oxygen, carbon dioxide, and a small trace of carbon monoxide
Venus and Mars haveatmospheres mostly consisting ofcarbon dioxide.
Mostly made of Carbon Dioxide(Co2).
Carbon Dioxide at .033% The only other two sources in the atmosphere are methane and carbon dioxide both of which are much less abundant.
It depends on what you mean. If you mean made up of as in the material that the surface mostly is then none that I know of. If you mean atmosphere then you have Venus, Mars, small amounts of it on Earth and probably on all the gas giants. Mercury and Pulto have thin atmospheres of nitrogen.
Mars has an atmosphere with low air pressure which is mostly carbon dioxide.
It is mostly carbon dioxide, 97 %, at a pressure 90 times that of earth's atmosphere at sea level.
Mars
The atmosphere on Mars is mostly carbon dioxide.
Venus' atmosphere is made up mostly of carbon dioxide, it lacks oxygen, and it only has a little nitrogen. Carbon dioxide makes the atmosphere heavy, which makes the atmospheric pressure 90 times stronger than Earth's atmospheric pressure. The atmosphere of Venus is very hot and thick.
That's MARS.
very thin and made mostly of carbon dioxide.

Mars & Venus
Mostly Carbon Dioxide
Venus is the same size as Earth and has no moons and has a thick atmosphere of mostly carbon dioxide.
