L1, L2 & L3 are "metastable". That is, anything placed at them will
only stay there as long as nothing disturbs them. If they move at all
off the point, they'll drift farther away.

L4 & L5 are "stable" anything that drifts off the point will tend to
drift back as long as it doesn't drift too far.

So L1, L2 & L3 are like hilltops. You can place something there but
if it gets nudged much it'll roll away.

L4 & L5 are more like depressions. Thing will tend to roll back to
them unless pushed far enough to go over the "rim".

So you won't find rocks and dust at L1, L2 & L3. You will at L5.
