Lonely Planet
From when it was discovered to when it was declassified as a planet, Pluto did not make a full orbit around the sun. Pluto was discovered in 1930 using the Lowell Observatory in Flagstaff, Arizona, and reclassified as a "dwarf planet" in 2006. Pluto takes about 248.09 Earth years to complete one full orbit around the Sun. If you're curious when Pluto will make its first full orbit, it will be on Monday, March 23, 2178.
