Pluto was discovered in 1930 and is the ninth-largest known object to freely orbit the sun. It is smaller than our Moon, and smaller than six other moons belonging to Jupiter, Saturn, and Neptune. Originally considered to be the ninth planet, Pluto was reclassified as a "Dwarf Planet" in 2006.
Pluto is currently in the constellation Capricornus at magnitude 14.4. It requires a fairly large telescope to be observed visually, but can be picked up photographically with modest equipment.
