There Might Be a Secret Planet Y Beyond Neptune

🪐 What if our solar system isn’t complete? Scientists now believe there might be a secret Planet Y hiding far beyond Neptune — a dark, distant world shaping the orbits of icy objects on the edge of our system. We’ve never seen it, but its gravitational pull is hard to ignore. Could it be a missing planet, a rogue world... or something stranger? Join us as we explore the theories, evidence, and the hunt for what could be the biggest discovery in modern astronomy.
