What is the last extra solar planet found?
Answers:
Pluto was the last to find and the first to go. Discovered in 1930.

Weren't three found orbitting on the far side of the sun?
Depends on what a planet is I guess. There have been some minor planets found within the last couple of years - Sedna, Xena (until they change it), and I believe a new one called Eris. I think that these are all Kuiper Belt objects though.
Actually now there r 12 planets in our solar system they are:
the three more planets are:
1- Ceres : it is between mars and jupiter,it was discovered as astroid in 1801, with 580 miles wide but the new definition would return it to planet status ,it would be called THE DWARF PLANET.
2- Charon: it long termed a moon of Pluto but it is the largest planet in our solar system relative to the object it orbits with the orbital center of this two object system is actually in the space between them.
3- Xena : it is the most distant planet in our solar system with 1.490 miles wide with an uncertainty of 60 miles meaning it's roughly the same size as Pluto.

Nobody has answered the question that was asked. Perhaps YA is not equivalent to a search of the literature.
The answer to this is a simple one - after 10 minutes of googling.
The planet is currently called HAT--P-1-b (sucky name). It is orbit around a star designated ADS 16402 B.
Ummm, extra-solar means in a different solar system, so why is everyone talking about this solar system? There are hundreds of extra-solar planets discovered - too many to keep up with. Also, the problem is, they are only speculating that the planets are there, they are too far away to see with a telescope, even the hubble. They take guesses based on their understanding of how the star they revolve around wobbles, so maybe some are really there and maybe others aren't we really don't know for sure.
Also, if you want the best astronomy program available go to http://www.shatters.net/celestia. - it is absolutely free and beats any program that you can buy in the stores. You can travel to any star, planet, and satellite that we know about.
The previous comment is correct.. the question is not about our solar system.
According to the NSAS New Worlds database, link below, the latest discovery was HIP 14810 b discovered in July 2006
Dist. from Earth (light-years) 171.9
Mass: 3.84 * Earth mass
But they find them quite regularly. So far, the rule on whether they're planets or dwarf planets, or brown dwarf stars isnt entirely fixed. so all extrasolar planets are considered planets, even if they're pluto sized. Of course, chance of us finding something that small orbiting another star is VERY small right now. We'll have to wait until the space missions are launched to search for planets from outside our atmosphere.
COROT will be the first, then Kepler and then either TPF or Darwin (or a combination if ESA and NASA get together).
