new world in our solar system

Exciting news! In recent years, astronomers have discovered intriguing evidence suggesting there may be a new world (or undiscovered planet) lurking in the outer reaches of our solar system. Heres what we know so far: The Hypothetical "Planet Nine" (or "Planet X") Evidence: Strange gravitational perturbations in the orbits of distant Kuiper Belt Objects (KBOs) hint at a massive, unseen planet. Predicted Size: 510 times Earths mass, likely icy with a highly elliptical orbit. Orbit: Could take 10,00020,000 years to circle the Sun, far beyond Neptune (500 AU or more). Other Recent Discoveries Dwarf Planets: Smaller worlds like Goblin, Farout, and Farfarout have been found in the outer solar system, but none match the theorized Planet Nine. New Moons: Uranus and Neptune recently had new moons confirmed, showing our solar system still holds surprises. Ongoing Searches Telescopes like Vera C. Rubin Observatory (2025) and Nancy Grace Roman Space Telescope may finally spot this elusive world. Some theories suggest Planet Nine could be a primordial black hole (!), though this is speculative.
