  1. Question

    Is there another undiscovered planet/brown dwarf within our solar system (I am not refering to Nibiru) If so, what is the possibility that this could have an eccliptical orbit, following Kelper's Law?

    There is nothing as large as a major planet or brown dwarf that remains undiscovered in our solar system. Undoubtedly, however, there are many undiscovered dwarf planets (including some as large as Pluto or Eris) that remain to be found in the region beyond Neptune. All these objects, whether you call them dwarf planets, or Trans Neptunian Objects, or comets, are in elliptical orbits. All objects orbiting the Sun follow ellipses, as first shown by Johannes Kepler 5 centuries ago. David Morrison
