Abstract

The article discusses the possibility of an undiscovered planet, potentially a "super-Earth," in our Solar System, particularly in the region beyond Neptune where objects like Sedna and 2012 VP113 are located. Sedna and VP113 exhibit unusual orbits that suggest they may have been influenced by a larger, unseen body, possibly a planet that has not yet been detected. The article outlines various hypotheses regarding the origins of these objects, including the idea that they may have been ejected from other solar systems or influenced by the gravitational pull of a distant planet. It also touches on the evolving definition of a planet, which led to Pluto's reclassification as a dwarf planet in 2006, and emphasizes the need for further discoveries to understand the dynamics of our Solar System.
