Features: Compared to the vast universe, our Earth is just a tiny speck in the vast ocean; compared to the celestial bodies and their ages, human history is merely a fleeting moment. However, driven by the curiosity to explore the unknown and with human ingenuity, we have already and will continue to recognize and understand the mysteries of the universe. — Professor Li Jing from the National Astronomical Observatory of the Chinese Academy of Sciences
Besides Earth, there are eight other planets—Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto—that revolve around the Sun, forming the solar system family together with the Sun. Earth is just an ordinary member in this family. Since the 1960s, humans have used advanced technology to launch various space probes to visit neighboring celestial bodies. Not only have we broadened our horizons, but we have also unraveled some mysteries of the solar system. Today, let’s join Grandpa Doctor, Doudou, and the Little Stars as we visit these "brothers and sisters" in the solar system family and share the remarkable achievements of human exploration in the planetary world. This is a great opportunity that we can’t miss!
