Mars is often called the "Red Planet" because of its red soil. It is the fourth planet from the Sun and is very similar to Earth. A day on Mars is almost as long as a day on Earth—about 24.6 hours.
Scientists are very interested in Mars because they think there might have been water on it long ago. Now, there is only ice at the poles. Many spaceships have been sent to Mars to take photos and collect information. In 2021, China sent its first Mars rover, Zhurong, to explore the planet.
Living on Mars would be very hard. The air is thin and there is no oxygen. The temperature can drop to -63 degrees Celsius at night. But scientists are working hard to find ways to make Mars a place where humans can live one day.

A. Because it has red water. B. Because of its red soil.
