Take a self-guided tour through the very building where Pluto was discovered!
During open house hours at the Pluto Discovery Dome, you can check out the 13-inch astrograph that was built specifically to aid in the search for Percival Lowell’s fabled ‘Planet X,’ and was eventually used by Clyde Tombaugh to discover Pluto in February of 1930. An educator will be present to answer your questions about the mysterious dwarf planet and its discovery.
Included with General Admission.
