Features: Besides Earth, there are eight other planets—Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto—revolving around the Sun. Together with the Sun, they form the solar system family. Earth is just an ordinary member of this family. Since the 1960s, humans have used advanced technology to launch various space probes to visit "neighbors" far and near. This has not only broadened our horizons but also solved some mysteries of the solar system. Today, join Grandpa Doctor, Doudou, and Little Star as we visit the solar system family and its "brothers and sisters," sharing the rich achievements of human exploration of the planetary world. This is a great opportunity that we can't miss!
