As @PeterErwin's comment compassionately points out:
"Acceleration" means changing the velocity vector, so an object in a circular orbit is always "accelerating" (because the direction of the velocit …

In the Modified Theory of Newtonian Gravity or MOND, they say that massive objects, accelerating slowly, experience this modified gravity.
But are they actually gaining in velocity, albeit very slowly …

Are short-period comets more stable (in their orbits) than long-period ones?
Why the sharp distinction between short-period (P) comets of less-than-200-year orbits and those (C) with even slightly longer ones?
To explore the possibility that it has to do with stability, I will …
