Planet X Resurgence

The theory of Planet X saw a revival in the early 2000s with the discovery of Sedna, a distant object that challenged traditional definitions of a planet. Sedna's highly eccentric orbit, along with other trans-Neptunian bodies like 2012 VP 113 and Leliaku Hanua, raises questions about their formation and the gravitational influences at play. These unusual orbits defy explanation by known planetary forces, suggesting the presence of unknown factors affecting their trajectories.
