@noob51beta , that's a cool idea. At some point I want to add real-life spacecraft (Voyager 1, New Horizons, etc.) with their real historical navigation paths. Those took years but maybe we could have 1 yr/day time compression to get the effect you are describing.
@cybereality , we have a few systems to take care of that. The main thing is that we dynamically adjust camera near
and far
so we can zoom in to km-sized objects or out to 3x1010 km. The other trick is that the camera parent body is always at global translation (0,0,0). That keeps Pluto from shaking wildly from lack of float precision.
