I know, i know Uranus isn't pronounced that, but what about the planet named "Anus". I dont know how to deal with it. 
Well, it is the last part of "Uranus," so perhaps Uh-nus or Ah-nus.
I personally find it quite amusing, but following the same line of reasoning "Uranus" itself may also be considered offensive, so I'm not too bothered by this name.
