Because Pluto has an orbit around the Sun which is very elliptical, there are times when it crosses Neptune's orbit and becomes closer to the Sun than Neptune. For 20 years, from 1979 to 1999, Neptune was actually farther from the sun than Pluto. For now, Pluto is back to being farther from the sun. It will be more than 230 years before Neptune and Pluto trade places again. Pluto slips inside of Neptune's orbit once every 248 Earth years for a period of twenty years. 1  Javascript must be enabled to use Cool Cosmos.
It varies hugely. Pluto follows the most eccentric orbit of all the planets. The closest Pluto gets to the sun (Perihelion) is 4,437,000,000 km while the furthest it gets from the sun (aphelion) is 7,311,000,000 km. Earths orbit is much more circular with a perihelion of 147,095,000 km and an aphelion of 151,930,000 km. For distance between Pluto and Earth :-.
