Pluto orbits the sun at a distance that varies from 4.4 to 7.4 billion kilometers (2.7 to 4.6 billion miles). In comparison, the Earth orbits at only around 150 million kilometers from the Sun. Because of the greater distance, Pluto takes around 248 Earth years to complete a single orbit of the sun. Since Pluto was officially discovered in 1930, it has only completed around a third of its total orbit since discovery.
Pluto was originally considered a planet, but in 2006 was reclassified as a “dwarf-planet” after it was discovered that there were several other objects of a similar or larger size in orbit. Eris, another dwarf planet which is currently thought to be larger than Pluto, takes 558 years to orbit the sun.
