The invisible force warping the paths of our solar system's outer edge
In short: Astronomers have spent over a century searching for a massive, hidden world that defies detection. This video explores why gravitational evidence suggests a giant planet exists, yet remains stubbornly invisible to our most advanced telescopes.
Deep in the outer solar system, approximately 500 astronomical units from the Sun, the orbits of numerous icy worlds appear warped and twisted. Mathematical models suggest this is caused by a hidden planet on a massive, elongated orbit, potentially reaching up to ten times the mass of Earth.
Despite a century of surveys and telescope sweeps, no direct photograph has been captured. The discrepancy between our ability to image distant exoplanets and our inability to find this local giant creates a profound mystery in modern astronomy.
