I heard that we're losing our moon, its slipping away from us in such tiny imperceptible steps that we don't notice any significant change even over kiloyears.
The same must apply to planets, inching ...

How much mass was deposited on a terrestrial planet during the Late Heavy Bombardment (LHB)?
Is it possible to estimate a reasonable interval, specifically, for Mars?
Could the mass addition to Mars ...
