both have 95%of carbon dioxide. Both are rocky worlds with a CO2 atmosphere. Both lie within our sun's habitable zone. Venus is about the size of Earth, while Mars has the same surface area as that of the earth's dry land.

Venus's atmosphere is 93 times heaver than Earth's, the air is mostly carbon dioxide, the planet is covered in sulfur dioxide clouds,and ground temperatures reach 860 degrees. And yet lightning works exactly the same way on both planets.

It has 81% the mass of Earth, while Mars only has 10% the mass of Earth. The climates of Mars and Venus are very different, and very different from Earth as well. ... This temperature difference comes from the fact that Venus is closer to the Sun, but also because it has a thick atmosphere of heat trapping carbon dioxide.

Why are the atmospheres of Venus, Earth and Mars so different? We think it all has to do with their distance from the Sun and their masses. Venus, the closest, was too hot to support large bodies of liquid water. ... All that remains behind are the heavier components to that original atmosphere including carbon dioxide.

The atmosphere of Venus is very hot and thick. ... The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases.

Two nearly identical spacecraft around Mars and Venus have compared the two worlds' atmospheres and found them to be surprisingly similar. ... "Venus's atmosphere is very thick, dry and hot, and Mars' atmosphere is very thin and cold. And yet the same processes are happening on both planets."

The four inner planets -- Mercury, Venus, Earth and Mars -- share several features in common. Astronomers call them the “terrestrial planets” because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth.
