Since Pluto is now a dwarf planet, the last planet is now Neptune.

The most recent planetary discovery occurred in 1930; the newly discovered body was named "Pluto". Since then, it has completed about 1/3rd of a revolution in its orbit around the sun.

Nobody can say with certainty that Pluto is the 'last' planet, only that it is the one most recently discovered, the one at the largest known average distance from the sun, and the one with the longest known orbital period.

So far....

The last true planet to be discovered was Neptune.

Pluto was found years later, but it recently lost its "planet" status.

The farthest planet from the sun is Neptune.

(It used to be Pluto, but Pluto isn't considered a planet anymore. It's a dwarf planet.)
