I'm guessing that there won't be a whole lot to see on Pluto, it will most likely appear like some of the moons of Saturn, basically a large white ball of frozen gases and rock. But it will nice to finally round out our “picture album” of all the planets in the solar system (and yes I know Pluto got downgraded to proto-planet status, but I went to school when we still had nine planets and Pluto will always be a planet in my mind.)

I remember watching a documentary some years ago about Pluto, and they think that it may become liquid as its orbit comes closest to the sun. If that’s the case, that would be really interesting and exciting.

Or it will look similar to Neptune’s moon, Triton, since they are considered to have formed similarly, are almost the same size, and Triton was captured rather than formed around Neptune.

Seeing the entire Pluto system will be something. How can such a small dwarf planet have so many moons?

I don’t think Pluto will be all white, since we already have a low resolution image of Pluto that shows otherwise.

Here is the view of Pluto from the Hubble telescope:

So it won't be a white ball, but frozen gases or rock should be expected.

The big difference is that Pluto will be the first object viewed up-close that is from the outer part of the solar system. It could be quite different from the gas giants and rocky planets of the inner solar system.

Factoid: Some of the ashes from the discoverer of Pluto, Clyde Tombaugh, are in the satellite that will pass by Pluto.
