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.
Pluto and Earth both orbit the sun, so they get closer together and farther apart every year. The closest together they can ever be, when Pluto is at perihelion and both planets are on. the same side of the sun, is 4.285 billion kilometers, or about 0.000453 of one light year. The farthest apart they can ever be, when Pluto is at aphelion and the planets are on. opposite sides of the sun, is 7.4653 billion kilometers, or about 0.000789 of one light year.
