That’s why Mars is colder than Earth. The temperature on Mars is about minus 63℃; here The temperature is about 14℃ on average. Although the two planets have many differences, they have something in common — water. On Mars, there is a lot of ice under the ground; On earth, we have water both on and under the ground.

Earth and Its Neighbor — Venus
Among the eight planets, Venus is also Earth’s neighbor.
Venus is smaller than Earth. It has a diameter of around 6,800 kilometers and Earth’s diameter is around 13,000 kilometers. Venus is closer to the Sun than Earth, at a distance of about 108 million kilometers. So it is much hotter than Earth. And the average temperature on Venus is around 464℃. The temperature on Earth is neither too hot nor too cold. It is about 14℃ on average. There is much water on Earth while there is no water on Venus. So no living things can survive on Venus.
Now humans are still exploring the Venus to know more about it.
