Draw a diagram showing the orbit of Earth and the orbit of Earth's Moon. Label the Sun, Earth, the Moon, Earths' orbit, and the Moon's orbit.

The Sun and Earth each exert a gravitational force on the Moon. What is the ratio F_("sun")//F_("Earth") of these two forces? (The average Sun-Moon distance is equal to the Sun Earth distance.)

The garvitational force exerted by the sun on the Moon is greater than that exerted by the Earth on the Moon. Why then does not the Moon escape from the Earth, during solar esclipe?
