In the cold outer reaches of the solar system, Princeton researchers have identified a small, icy world — catalogued as 2017 OF201 — that takes 25,000 years to complete a single journey around the Sun. Its discovery does not resolve the long-standing search for a hidden giant planet beyond Neptune, but rather deepens the mystery, as its orbital path defies the very pattern that was meant to prove Planet Nine's existence. Science, as it so often does, has answered one question by quietly opening several more.
