Suppose you design an experiment where you need to minimize the effects of tidal forces. Where would you go? There are a few possibilities, and the choice depends on how much effort you are willing to make. My reasoning goes like this:
Maximize the distance from any centers of masses, i.e.
- Climb Mount Everest
- Go in Low Earth Orbit
- Go in even higher orbits
Use properties of a many-body system where the gravitational field has a minimum
- Equilibrium point between Earth and Moon
- Other Lagrange Points of the Earth/Moon system (Are they better, i.e. have a lower delta a/delta x?)
I can think of more places farther out, like where the Jovian Trojans orbit the Sun. Of course, the further away from the Sun you get, the better. But maybe there are closer spots I have overseen where tidal forces are extremely low.
