Since the Neptune Orbiter thread has started to veer into talking about a Uranus orbiter as well, it seemed like a good idea to start a topic for Uranus.

Just keep in mind that -- because Pluto's gravity is so weak -- its atmosphere, thin though it is, towers up and up and up above the surface, with a huge scale height. In fact, there is speculation that some of it may get exchanged with Charon through tidal forces! High-altitude aerocapture in this situation is quite practical, if you have a moderately-sized ballute. (Ditto for Triton.)
