Pluto, which is four billion miles from Earth, is probably the most mysterious object in the solar system.

"Pluto is really the last unexplored body of the solar system," said Schiele Museum and Planetarium Director Jim Craig said. "It's really sort of the last time we're going to be seeing something for the first time."
