Correct usage of the term 'gravity'

Question

If I want to make clear that one object is being affected by the gravity of another object, for example the Earth and the moon.

Would I say:

The moon has a gravity, just as all mass does.

or, would I say:

The moon has gravity, just as all mass does.

Generally one speaks of a gravitational field surrounding any massive object; but gravity itself is like force, motion, mass, and many other physical concepts -- an abstract (and therefore mass) noun. — John Lawler, Mar 3, 2015 at 19:13
This seems like a very clumsy sentence. Perhaps you should consider rewriting whatever it is you're trying to say so that you can avoid its usage. — Ian MacDonald, Mar 3, 2015 at 19:14
Rephrasing the sentence as The moon, like all mass, has gravity. might make it sound more natural. — Nicole, Mar 3, 2015 at 19:35

The second is correct. Rarely would you ever put 'a' before gravity.
