There is no newest planet in our solar system, they all have been there for billion of years. Now if you mean the newest discovered planet, that would be Neptune, discovered in 1846.
Additional bodies have been discovered since then, but those are now classified as dwarf planets, or as Kuiper objects, and so on.
Eris was discovered in January 2005 on images taken two years earlier, and is a bit larger than Pluto; but it was not named Eris until April 2006. Since then, more dwarf planets were discovered, the latest that I know of is still only referred with a code name 2005 FY9 (but nicknamed Easterbunny), discovered in April 2005. More will be found in the future.

Newest Member of Our Solar System
artist's concept of planet catalogued as 2003UB313
Image above: This artist's concept shows the planet catalogued as 2003UB313 at the lonely outer fringes of our solar system. Our Sun can be seen in the distance. The new planet, which is yet to be formally named, is at least as big as Pluto and about three times farther away from the Sun than Pluto. It is very cold and dark. The planet was discovered by the Samuel Oschin Telescope at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005. Image credit: NASA/JPL-Caltech

The most recently discovered planet is called Neptune. It was discovered on September 23, 1846. There have been other objects that have been called planets, but have since be re-classified.

There hasn't been a "newest" planet since the 1700's.

Hey Scooter, haven't you been keeping up? Not only is there not a "NEW" planet, we officially lost one. Pluto is no longer classified as a planet. We now only have eight official planets. Hellooooo.

Zotar 739. But, it still questionable as to whether it a Planet or Space Ship as it seems to have no defined orbit or consistent speed.

Pluto is no longer clasified as a planet so Neptune was the last.

If you mean the most recently discovered, that would be Neptune.
If you mean the most recently created, that would be none. All were formed at the same time.
