Neptune has always been the farthest planet, but we didn't always know that.
On August 24, 2006, when the International Astronomical Union (IAU) defined what it means to be a "planet", Neptune earned it's badge as the most distant (from the sun) planet in our solar system.
Prior to that, when Pluto was referred to as a planet, it last crossed inside of Neptune's orbit on February 7, 1979 leaving Neptune as the most distant planet until February 11, 1999.
Pluto's orbit crosses inside of Neptune's orbit for 20 years out of every 248.
