For decades, astronomers have believed that an as-yet-undiscovered planet may be lurking in the farthest corners of the solar system.
Astronomers continue tracking an unseen celestial body know as Planet Nine in the furthest affects of the solar system. The search focuses on gravitational signatures detected beyond Neptune. Telescopes first confirmed Neptune in 1846 after mathematical predictions identified gravitational anomalies affecting the orbit of Uranus. Astronomer Clyde W. Tombaugh later discovered Pluto in 1930 [...]
