Is There A HIDDEN Massive PLANET in Our Solar System?

The video discusses the potential existence of "Planet Nine" in our solar system, a theory based on unusual orbits of Uranus, Neptune, and certain Trans-Neptunian Objects (TNOs). This hypothetical planet could be 4-10 times Earth's mass and located far beyond Neptune's orbit. Its detection is challenging due to its distance, size, and dimness. Various theories about its formation include ejection from the inner solar system, capture from another star system, or its existence as a rogue planet. Its composition may vary from a rocky super-earth to a mini gas giant. The planet's existence remains unconfirmed, but advanced telescopes like the James Webb could potentially facilitate its discovery.
