Mercury is the first planet from the Sun. It’s small and has a lot of craters on its surface. Read the text about Earth and Mars and complete the table.

Activity 2 Earth and Its Neighbor—Mars Is there any life in outer space We may think of the same planet—Mars. Do you know Mars What do you think Mars is like I know Mars! It’s often called the "Red Planet" because its soil has iron oxide—basically rust—which makes it look reddish. 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. What’s Mars’ approximate diameter 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 than Earth.
