#mutantpen 10- Lowell The astronomical symbol for Pluto are the initials of Percival Lowell; the American astronomer devoted the last years of his life to the search of Planet X that he believed was disrupting the movements of Uranus and Neptune; Clyde Tombaugh discovered Pluto at the Lowell Observatory, founded by Percival Lowell, in 1930 but the observatory took pictures of Pluto in 1915, without anybody realising Pluto was not a star.
