I thought it was the moon (and the sun) contributing a quadrupole term to the Earth’s gravitational potential. Silly me.

“BONUS FACT:
The sun also causes tides on the earth, but they’re only about half as strong as the moon’s”
@Ben Banana
The moon slightly in excess covers the sun in a total solar eclipse. One might then posit that their effective local masses are nearly identical for being nearly the same apparent size. Correct for average densities, 3.344 g/cm^3 vs. 1.408 g/cm^3 respectively. That ratio is 0.42 (and a little bit more).

The given ratio is 0.44,

Or maybe 0.465. Verify the constants and respect sig figs.
