http://www.sciencemag.org/news/2016...eptune-sized-planet-lurks-unseen-solar-system Pretty cool stuff, even though it's probably just another gas giant that won't be useful to humans for hundreds of years, if we even make it that far. Leave Pluto alone, Mike Brown.
Pluto as a planet is mediocre. In stead, we should appreciate pluto as the first binary dwarf planet, which is #1 unique in the solar system and #2 WAY COOLER THAN A PLANET As to Planet X, meh i'll get hyped when we get actual results.
