is world famous for his
discovery of the planet Pluto in 1930 [Pluto].
Clyde had a life filled with astronomy and many discoveries.
He was also a believer in UFO's.
Did you know that Pluto is
officially no longer a planet? It is now a Dwarf Planet
and one of the many Kuiper
Belt objects [KB],
but with its own classification as a Plutoid [Plutuid].
Interestingly, a young girl from England suggested the name "Pluto"
via an Oxford professor.
Astronomers knew that "PL" would also respect Percival
Lowell's planet search, later handed to Clyde.
