Newton's Law in full fixed-coordinate vector form:

where

If we bring many point masses into the picture, we just add up all the forces:

In the limit that the point masses get so packed together that they can be treated as constituting a spatial continuum of mass, the sum becomes a volume integral:

where

You can also use Poisson's equation for the gravitational potential.

questions:

what effects on the general motion of the earth are due to its non-spherical symmetry?

astrophysicists will take account of this....

Even artificial satellites are definitely not spherically symmetric objects (although relatively small): as we can account for this?

In my mind the easiest way ...

A tangible example, the moon will not be a celestial body in perfect spherical symmetry. How this affect on its motion around the earth?

thanks
