New mystery “planet” on the horizon? Here’s why planet ‘Y’ could be warping our Solar System

Recent research suggests a warp in the orbital plane of Trans-Neptunian Objects (TNOs) between 80 and 400 AU, hinting at the gravitational influence of a potential Planet Y. This hypothetical planet, smaller than Earth, could be orbiting at 100-200 AU. The Vera Rubin Observatory’s LSST may soon confirm or deny its existence and further detail the Kuiper belt’s warp.
