Compare the forces with wich the Sun and the Earth act on the Moon.
How can you explain the fact that the Moon is a satellite of the Earth, although the attraction of the Sun is stronger?

Answer

The Sun attracts the Moon 2.1 times more strongly than does the Earth.

Explanation

The force ratio south is
`(F_(o.))/(F_(o+)) = (gamma m M_(o.))/(R_(o.)^(2)) : (gamma mM_(o+))/(R_(o+)^(2)) = (M_(o.)R_(o+)^(2))/(M_(o+)R_(o.)^(2)) ~~2`
The reason that the Moon is a satellite of the Earth despite the fact that the Sun.s gravitational attraction is twice as strong is found in the initial conditions, the Moon.s initial coordinate and initial velocity at the time the Moon found itself in the gravitational fields of both bodies.
