A group of French scientists have said they are closer to pinning down the location of Planet Nine, the mystery potential new addition to the list of major satellites orbiting the Sun. US astronomers announced in January that they may have found a ninth planet beyond Neptune 10 times the mass of Earth, but said it could take 10,000 to 20,000 years to orbit the Sun and they had no idea where it might be. https://www.theguardian.com/science...e-along-sprawling-orbit-of-thousands-of-years I hope we'd call it Yuggoth once it's found.
Having grown up with Pluto being a planet, I feel odd whenever Neptune is labeled as the last planet outwards ... but regardless of the classification, finding another big satellite of our sun is a thrilling thing.
NASA's Cassini probe, which has been exploring the Saturn system for more than a decade might help with the hunt for the Ninth Planet: http://www.space.com/32037-saturn-probe-cassini-planet-nine-search.html
Update: Using observations from the Cassini spacecraft, a team of French astronomers have been able to specify the possible positions of a ninth planet in the Solar System. Analysis of radio data from the Cassini spacecraft defines forbidden areas (in red) where the perturbations created by the planet are inconsistent with observations, and a likely area (green) where the addition of the planet improves the model prediction, reducing the differences between the calculations and Cassini data. The position of minimum residues is the most likely location for a planet at P9. Scales are in astronomical units (AU).

New evidence strengthens the idea that there is a hidden planet sitting at the edge of our solar system. Objects have been spotted moving around unusually at the edge of our solar system. And the best explanation for the strange orbits is the mysterious Planet Nine, according to Mike Brown, one of the scientists who has argued that the hidden planet exists. He says that he has tracked another object in that Kuiper Belt that is also moving unusually. And its strange movement is exactly how what would be expected if Planet Nine is real. None of these claims has yet been published in a peer-reviewed journal or checked by other scientists. But the Canada France Hawaii Telescope is currently conducting the Outer Solar System Origins Survey, looking far into our solar system, and so will be able to check the claims as more Kuiper Belt objects are discovered. http://www.independent.co.uk/news/s...itting-at-the-edge-of-our-solar-a6954986.html
