In 2015, the New Horizons spacecraft gave us our first close look at Pluto, the most famous dwarf planet in the outskirts of our Solar System. The pictures sent back to Earth reveal a world far more complex than anyone realized. Now scientists are making new discoveries about our Solar System—and what it may be hiding: an object 10 times more massive than Earth far beyond the orbit of Neptune.
