Moon tidal force across Earth
The Moon tidal force across Earth is the difference in lunar gravitational pull between the near and far sides of the planet, which drives ocean tides.
Also known as: lunar tidal force on Earth
How big is it?
6.6 × 10¹² MN of force
Defined differential-force scale · derived calculation
Typical recorded range: 6 × 10¹² MN to 7.2 × 10¹² MN.
A little perspective
Earth gravitational pull on the Moon is about 30 times larger on this measurement.
Earth gravitational pull on the Moon: Earth’s gravitational pull on the Moon is the force that keeps the Moon in orbit around the Earth.
Measurements, assumptions & sources +
Moon tidal force across Earth
Approximately 6.6 × 10¹⁸ N, a teaching scale formed by multiplying Earth’s mass by the near-to-centre lunar tidal-acceleration difference 2GMₘRₑ/r³. It is not the Moon’s total attraction on Earth and ignores solar tides and Earth deformation.
Defined examples — our methodology
The marked defined differential-force scale is calibrated. Unmeasured illustration details are representative.
Earth gravitational pull on the Moon
Approximately 1.98 × 10²⁰ N, calculated with F = GMm/r² using JPL Earth and Moon masses and the 384,400 km mean centre-to-centre separation. The elliptical orbit changes the instantaneous force.
The marked mean-separation gravitational force is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 6.6 × 10¹² MN
For comparison, this page uses defined differential-force scale. The record labels the measurement derived calculation; that status is retained wherever the value is compared. The recorded range is 6 × 10¹² MN to 7.2 × 10¹² MN.
