Snarkiverse (for those unfortunate enough not to have seen it) puts the stock KSP bodies in interesting orbits Principia simulates the Newtonian mechanics of orbits, rather than using the patched-conic approximation. This raises several interesting questions: + Mun passes very close over KSC every second day. Does this give noticeable advantage to well-timed launches (like launching at high tide)? + Pol orbits very near Duna.  Will she break up under tidal forces? + Eeloo orb
