Is Neptune sometimes the farthest planet?

Because Pluto has an orbit around the sun which is very elliptical, there are times when it crosses Neptune's orbit and becomes the 8th planet from the sun instead of the 9th. When this happens, Neptune becomes the 9th and farthest planet in the solar system. For 20 years, from 1979 to 1999, Neptune was actually farther from the sun than Pluto. For now, Pluto is back to being the 9th and farthest planet 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.
