Is it possible that meteor bombardment of the moon may add weight/mass and affecting tide drifts?

Question

Add meteoric mass to a lunar body must have some type of added gravitational effect. Perhaps creating abnormal flooding in areas that rarely know of flooding.

True or false.

I only surmise.

Answer 1

false.

It is true that in-falling matter adds mass.

This added mass is extremely small compared to the Moon's total mass.

The Moon is receding at a rate of 4 cm per year.  This certainly makes a bigger effect than the added mass.

The tidal "force" is directly proportional to the mass (double the mass, double the force).

However, it is inversely proportional to the CUBE of the distance (double the distance = 1/8 the tidal force).

Answer 2

True technically, but not really significant.

Lets assume meteors add perhaps a million kg to the moon's mass each year.  That sounds like a lot, but the moon's mass is 7.3477 x 10^22 kg - a million kg is a tiny TINY fraction of that and will have no effect on the moon's gravity.

Even over a million years, that's still not very much - and since the moon is receding from the Earth each year (not by much, but its still receding), any gravitational increase due to increased mass gained from meteors is more than offset by the increasing distance of the moon.
