A tiny object far beyond Pluto, newly discovered by the Subaru Telescope, could reshape our understanding of the early Solar System. Named 2023 KQ14, this rare “sednoid” follows an unusual orbit that doesn’t match its known cousins—hinting at ancient celestial upheavals, and possibly even challenging the existence of the elusive Planet Nine. With a stable path lasting over 4 billion years, this cosmic time capsule opens a new window into our system’s chaotic youth.
