Which planet's atmospheric environment is closest to the earth?

The environment most similar to the earth's surface is Mars. Although Venus is most similar to the Earth in size and mass, it is actually Mars that is most similar to the Earth's surface environment. Mars, like the earth, is also a rocky planet covered by the atmosphere, with diverse topography, including mountains, plains and canyons, dry river beds and lakes, and sandstorms that rage from time to time, just like the desert Gobi on the earth.

A day on Mars is slightly longer than that on Earth. A Mars day is 24 hours, 39 minutes and 35 seconds. There are four seasons on Mars, but each season is twice as long as that on Earth. The temperature change on Mars is a little bigger than that on Earth. The average surface temperature is-55℃, the highest temperature is 27℃, and the lowest temperature is-133℃.

Mars, like the earth, was full of oceans, lakes and rivers in ancient times, but the thin atmosphere failed to retain water, which made the surface water of Mars disappear 1 100 million years ago. However, most scientists believe that there is still a lot of solid water in the polar regions of Mars, and there is also a lot of water underground.
