In the vast and boundless universe, humanity's exploration of the unknown has never ceased. From ancient times to the modern era, our understanding of Earth and the surrounding planets has deepened continuously. Since the 16th century, with advancements in science and observational technology, planets such as Uranus, Neptune, and Pluto have been discovered. However, some scientists believe that there may still be an undiscovered tenth planet hidden in the solar system. This unknown planet is referred to as 'Planet X,' sparking widespread interest and discussion.
The mysterious 'Planet X' not only fuels human imagination but also drives astronomers' enthusiasm for exploration. From William Herschel's discovery of Uranus in the 17th century, to the discovery of Neptune by Le Verrier in 1846, and Pluto by Tombaugh in 1930, each discovery has proven the power of human theoretical conjecture. Despite this, Pluto's mass is insufficient to explain the orbital deviations of Uranus and Neptune, prompting the continued search for this potentially existing tenth planet.
