Could there be a giant planet hiding in the Solar System?
About this episode
Beyond Neptune’s icy domain lies a shadowy enigma—Planet Nine, a giant world that may lurk at the edges of our solar system. Its existence is betrayed by the strange, clustered orbits of distant objects, hinting at a massive, unseen force.
Could this hidden planet be the remnant of cosmic chaos, or a rogue world captured from another star?
In this episode, we unravel the clues, explore its possible origins, and examine the revolutionary technologies searching for this elusive giant. Planet Nine’s discovery could rewrite the story of our solar system—and challenge everything we think we know about the cosmos.
