Question #16 – On this day in 1930, Clyde Tombaugh discovered Pluto. On July 14, 2015, a spacecraft flew 7,800 miles above the dwarf planet. What was the name of this spacecraft, and where is it now?
After taking many great photographs of Pluto and its five moons, the New Horizons spacecraft continued its mission flying more than 4½ billion miles beyond Earth to encounter the most distant object ever photographed "close up". The object's name, Ultima Thule, means "A distant, unknown region; the extreme limit of travel and discovery".
