Earth-Moon L1 tidal acceleration over one kilometre
Earth-Moon L1 tidal acceleration over one kilometre is the difference in gravitational pull experienced across a one-kilometre distance near the Earth-Moon L1 point.
Also known as: L1 tidal gradient over one kilometre, Earth Moon L1 gravity gradient
How big is it?
8.03 × 10⁻⁸ N of force
Equivalent differential force on a 1 kg body · derived model
Typical recorded range: 6 × 10⁻⁸ N to 1 × 10⁻⁷ N.
A little perspective
Gravitational attraction between two people one metre apart is about 3.74 times larger on this measurement.
Gravitational attraction between two people one metre apart: This is the gravitational force that two people exert on each other when separated by one metre.

Why this measurement?
Why we use 8.03 × 10⁻⁸ N
For comparison, this page uses equivalent differential force on a 1 kg body. This is labelled derived model: an explicit comparison model rather than a claim that every example has the same value. The recorded range is 6 × 10⁻⁸ N to 1 × 10⁻⁷ N.
