In the image above, the red oval represents the suggested path of an elusive planet called Planet X. Astronomers have been observing the orbits of objects in our Solar System and have decided there’s a strong possibility a ninth planet, almost the size of Neptune, is orbiting our Sun. Although Planet X has yet to be detected with any telescope, astronomers believe its orbit interacts with the orbits of other icy objects in the far reaches of our Solar System. In fact, there is only a 1 in 15,000 chance that the orbits of these icy objects would line up the way they do without the existence of a ninth planet. Planet X would be orbiting anywhere from 600 to 1,200 AU in its very elliptical orbit, and would take about 15,000 years to make one trip around the Sun. Astronomers are working on detecting Planet X with the help of the Keck and Subaru telescopes in Hawaii and are confident they will be able to detect it within the next five years or so.
