The modern hypothesis of a Planet X or Planet Nine, however, is based on more rigorous analysis of extreme trans-Neptunian objects (TNOs) that cluster in a specific region of the solar system, suggesting a gravitational shepherd much larger than Pluto. This search culminated in the discovery of Pluto in 1930, though Pluto was later found to be too small to significantly affect the orbits of the giant planets.

In 2006, the International Astronomical Union (IAU) established a formal definition of a planet, requiring it to orbit the Sun, be spherical in shape, and have "cleared its neighborhood" around its orbit.
Real Evidence for the 10th Planet in Our Solar System Today
Their trajectories are clustered in a way that is difficult to explain without the gravitational influence of a massive, unseen body. These efforts are methodically scanning regions of the sky where the planet is predicted to be, inching closer to either a discovery or a definitive conclusion that it does not exist in the predicted form.
