Detecting objects on the fringe of our solar system, objects that are so far away from the Sun that they do not reflect any of its light, has always been very difficult but these astronomers think their proposed planet has given its presence away by how it effects other objects nearby that we can detect. If the planet is really there then it will be the third, true planet discovered in our own solar system since ancient times. http://www.nbcnews.com/tech/tech-news/new-ninth-planet-may-have-been-detected-scientists-say-n500396
