Pluto was considered the ninth planet until 2006, when it was reclassified as a dwarf planet once it became clear the Kuiper Belt holds many similar objects. Its largest moon, Charon, is half Pluto's size — the two orbit a shared centre of gravity outside Pluto itself, which is why they're sometimes called a double dwarf planet. NASA's New Horizons probe flew past Pluto in 2015, the only mission to do so, and discovered the heart-shaped glacial plain Tombaugh Regio, among other features.
