What is the furthest planet from the sun

Pluto. All though I think it might do a little jig with Neptune from time to time.

[VHG]

Pluto is not a planet.

I guess it depends if you include "dwarf planets"

On August 24, 2006, the International Astronomical Union (IAU) defined what it means to be a "planet" within the Solar System. This definition excluded Pluto as a planet and added it as a member of the new category "dwarf planet" along with Eris and Ceres. After the reclassification, Pluto was added to the list of dwarf planets and given the number 134340.

might still be OGLE-TR-56b

I strongly object to people stealing planets from our lovely Solar System. Even if Pluto is just a dwarf planet then it is still one. It has a name and 3 moons and orbits the sun just like all the other planets. What more proof do you need? It would be cold for a holiday there as it is about 230 degrees celsius below zero.

planets outside of the solar system have been detected so it's not restricted to the usual suspects

Using that argument, then it's Eris (most the time) surely?

Ecclescake,yours is funnier, mine easier to remember

the furthest planet from the sun is OGLE-2005-BLG-390Lb http://en.wikipedia.o...solar_planet_extremes

the OP does not specify that it has to be this solar system

A much more logical mnemonic is "My Very Easy Method Just Speeds Up Naming Planets" - well, that's the one I use anyway...

The problem with Pluto was that it was going to get silly

The old rules for a planet was a body with sufficient gravity to form itself into a spheroid that was orbiting the sun.

Unfortunately so many new trans-Neptune bodies, some pretty large were being discovered that e'd be getting new solar planets too regularly.

Eris was the last straw as it was bigger than Pluto

So an additional criteria was added, that the planet must have cleared the vicinity of it's orbit of other bodies.

This makes Pluto and Eris and Sedna large Kuiper belt objects

Rubbish all of you. The most distant planet from the Sun is in a star system on the other side of the Universe.

[venator]

Quite right, Beso - it's actually been identified as the planet Koozebane
