Re: Phobos and Deimos
hmmmm....
I could grant their initial oblique orbits being 'equatorialized' by encounters with other debris (which has been cleared from near-Mars orbit since?), but... if the scenario resembles the impact theory of our Moon's formation, then the globs that became P & D should have been molten, and should have had time to assume a more spherical shape while cooling.
On the other hand: is there a class of near-Mars asteroids? Or perhaps more near-Earth types have Martian origin - more, that is, than the ones found after collision.
Vive l'esprit critique!
