sudnadja, #TravellerRPG : Pluto Tourism. I had to rerun the model because, apparently for years now, I had the incorrect GM values for both Pluto and Charon (Pluto is supposed to be about 869.61 km^3 s^-2 and I had about 874, and inverse for Charon. I still had a circular orbit of Charon, so I must have had old GM values somewhere - it's possible I set this (solar system config) up before the New Horizons flyby. Surface acceleration on Pluto should be about 0.614919 m/s^2. Adjust expectations accordingly
