Pluto and its moon Charon have something that doesn't exist anywhere else in the solar system

NASA's New Horizons spacecraft took us to Pluto for the first time in July 2015. Scientists are astonished by the incredible features they've observed on the dwarf planet, including a 1,000 mile wide region covered in nitrogen snow that resembles a heart. But we have reason to believe Pluto's heart is a bit warmer than the ice the covers it.
