2. Newton's equation of
universal gravitation
The Moon is much closer to the Earth
than the Sun. The distance from the
Moon to the Earth is 1/400 the distance
from the Sun to the Earth. Square it, we
get 1/160000.
(All numbers here are from reference books, and are
used as approximate numbers.)

3. but the mass of the Sun is unbelievably
big,
it is:(1.98*1030)/(7.35*1022)
=2.69*107 the mass of the Moon.
We offset the proportion and the inverse
proportion. The solar gravitational force
is about 168 times stronger than the
lunar. (We may have 162 if we use other numbers
for reference but this doesn’t affect the author’s
opinion here.)
