We Finally Found Evidence Planet 9 Is Real

In 2025, astronomers comparing two infrared maps taken 23 years apart found a single dot of heat that had quietly moved. If it is real, it is a planet bigger than Earth, hiding at the edge of our own solar system, and a new telescope in Chile may confirm it within a few years. Tonight we go out past Neptune to find the ghost planet, and the strange clues it has left behind. If you enjoy this kind of thing, hit like and subscribe so the next one finds you. Topics explored: Planet Nine, the Vera Rubin Observatory, the Kuiper Belt, the sednoids, and the hidden edge of the solar system.
