Another planet is suspected to be hidden on the edge of our solar system and two astronomers say their evidence points in that direction. Two scientists at the University of Arizona believe that a Mars sized planet could exist after analysing a swarm of small icy objects that extends beyond the orbit of Pluto. This is not the same as planet nine believed to be tugging at the orbits of the solar system's most distant inhabitants as proposed by another group of scientists but another planet - number 10. One of the researchers is Kat Volk.
