At Jupiter (ignoring its own gravity) = .000000000000000002 G's

As you can see, we'll never reach 0. Gravity will just drop off into
really, REALLY small numbers the farther out we go. Hope this helps a
bit.

Is this true? Gravity never quites get to 0? I am having one of those
moments. This is shocking. Can someone expound on this? The concept sounds
very important. How far can we actually measure before we can't "sense" the
field anymore?
