Features: Compared to the vast universe, our Earth can be considered a mere speck in the vast ocean; in contrast to 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 orbit 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 types of space probes to visit neighboring planets, not only broadening our horizons but also solving some mysteries within the solar system. Today, let’s join Grandpa Doctor, Doudou, and Little Star to visit these "brothers and sisters" in the solar system family and share the fruitful achievements of human exploration of the planetary world. This is a great opportunity that we can’t miss!
