Planet X

Planet X is a proposed hypothetical planet beyond Neptune in our solar system. It is suggested to explain unusual or clustered orbital patterns observed in small objects like trans-Neptunian objects. If it exists, Planet X would be large—possibly similar to Neptune or Uranus—and orbit far from the Sun with a highly elongated path. Its gravitational influence could account for the orbital anomalies seen among distant icy bodies. However, as of now, no direct observation confirms its existence, and it remains a subject of scientific investigation and debate.
