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 wide. Not only have they broadened their horizons, but they have also solved some mysteries of the solar system. Today, join Grandpa Doctor, Doudou, and Little Star as we visit the solar system family and meet these "brothers and sisters," sharing the remarkable achievements of human exploration of the planetary world. This is a great opportunity not to be missed!
