Two large, unknown planets could be lurking at the edge of our solar system, scientists believe – and observing the orbit of asteroids and ‘dwarf planets’ in a far-flung region beyond Pluto, at least one of the planets is believed likely to be larger than Earth.

The research, by University of Madrid scientists, suggests that two large objects may be lurking in a little-studied area at the ‘fringe’ or our solar system, known as the ‘inner Oort cloud’.

The first hints of their existence came from the discovery of icy ‘dwarf planets’ Sedna and 2012VP113 – and scientists studying their orbits realised their might be something massive on the edge of our solar system pulling Sedna and its fellow ‘dwarf planet’ out into the frigid depths of space.

The research highlights how little we actually know about the…
