Pluto is relatively small as planets go; it is officially categorized as a dwarf planet.

Pluto was founded by ancient Greek astronomers thousands of years ago. So I'll go with Pluto the planet, despite it now being a dwarf planet.
Pluto isn't a moon, it orbits the sun, but it is a dwarf planet
No probes have been to Pluto yet, but the New Horizons probe is currently on the way there.
It takes Pluto 248 Earth years to orbit the sun. (1 Pluto year = 248 Earth years)

Actually, No One Really Knows If Pluto Is Rocky. The Reason Why Is Because It Is Impossible To Go To Pluto Because It Is So Far Out Of Earth's Way.
Pluto is very cold and has little atmosphere. It has either ice or vapor so there is no liquid to swim in.
There are no plans to go to Pluto at present. It is also highly unlikely that any manned mission will be undertaken in the foreseeable future.
