Astronomers Just Detected an Object Moving the Wrong Way

#space #astronomy #solarsystem An entire planet may have been hiding in our own solar system for four and a half billion years. Astronomers just detected an object moving the wrong way, and its orbit is pointing at something massive in the dark. We follow the trail from the moment the telescope flagged the anomaly, through the gravitational forces that could flip an orbit entirely, to the hidden architecture of our solar system that no one expected to find.
