Color the Sun, Earth and Mars. Earth and Its Neighbor—Mars Is there any life in outer space? We may think of the same planet—Mars. Mars is smaller than Earth. It has a diameter of around 6,800 kilometers and Earth’s diameter is around 13,000 kilometers. Mars looks red because of its red soil, while most parts of Earth look blue because of its oceans. As a neighbor planet, Mars is farther from the Sun than Earth. Mars is about 228 million kilometers away from the Sun, while Earth is about 150 million kilometers away. That is why Mars is colder thar Earth. The temperature on Mars is about minus 63℃; here on Earth, the temperature is about 14℃ on average. Although the two planets have many differences, they have something in common—water. On Mars, there’s a lot of ice under the ground; On Earth, we have water both on and under the ground. Mars is waiting for us to explore, and so is the universe. Activity 2 Read the text about Earth and Mars and complete the table.
