The movements of a newly discovered dwarf planet beyond Pluto’s orbit, dubbed 2012 VP113, suggest that a mysterious frontier of the solar system may include a planet much larger than Earth.
Experts say the discovery could lead scientists to rewrite our understanding of the fringes of our solar system.
