Amazing solar system!
The solar system is big and wonderful. It has the Sun at the centre(中心), and eight planets go around it. Let's learn about some of these planets.
Mercury is the smallest planet. It is the nearest to the Sun. A day on Mercury is very long—about 59 Earth days! A year on Mercury is short, only 88 Earth days.
Venus is the hottest planet. Its surface is very hot, hot enough to melt some metal. Also, Venus spins the opposite(相反) way of most planets. So on Venus, the Sun rises in the west and sets in the east.
Earth is the only planet with life we know. It has water and air, and the temperature is just right for plants, animals and people to live. The Moon is Earth's only natural satellite. It makes the ocean tides move.
Mars is called the "red planet". Its soil is red and rusty(红褐色的). It has a very tall volcano(火山). It is almost three times(倍) higher than the highest mountain on Earth. Mars also has big dust storms(尘暴) that can cover the whole planet.
