American astronomer Percival Lowell proposed the existence of a ninth planet in 1902, primarily based on anomalies within the orbits of Uranus and Neptune.
Pluto was found by Claude Tombaugh on February 18, 1930, and was initially known as Planet X.
Present astronomers suspect there could also be one other undiscovered planet, doubtlessly bigger than Earth, situated within the outer photo voltaic system.
The “Kai mechanism,” a dynamic impact in celestial mechanics, might clarify the weird orbital behaviors of trans-Neptunian objects (TNOs) and recommend the affect of a bigger physique.
Proof for Planet X was steered in 2010, primarily based on discrepancies within the orbits of TNOs, together with Pluto, Eris, and Sedna.
The upcoming Vera C. Rubin Observatory, set to start operations in January 2025, is anticipated to assist within the seek for Planet X and its potential moons.
Some physicists suggest that Planet X may very well be a primordial black gap, which might account for gravitational anomalies with out being detectable by telescopes.
