Scientists Discover Exoplanet So Massive They’re Not Sure It’s a Planet

You know we’ve found something new and interesting when scientists don’t really know how to classify it. Using the Subaru Telescope an international team of astronomers has discovered a “super-Jupiter” so massive that it seems they’re not quite sure whether to call it a planet or a low-mass brown dwarf (in other words, a star that failed to fire). Located roughly 170 light-years from Earth, the host star is roughly 2.5 times more massive than the sun and its planet is about 13 times larger than Jupiter, making this the highest-mass star to ever host a directly imaged orbital companion–especially one of this size.
