Pluto's features named 87 years after its discovery
The International Astronomical Union has officially approved the naming of Pluto's 14 features, 87 years after the dwarf planet's discovery. Pluto's mountain ranges were named after Tenzing Norgay and Sir Edmund Hillary, the first to successfully climb Mt Everest. The names also honour Pluto's discoverer Clyde Tombaugh, and Venetia Burney, the then 11-year-old girl who suggested the name 'Pluto'.
