Why is the gravitational attraction of the Moon a greater factor in determining tides than the gravitational attraction of the much larger Sun?. Earth is much closer to the Moon than to the Sun.. The Sun s gravity is a factor only during the day. C. The Moon s core has a much greater density than the Sun s core.. The Sun s mass is smaller than the mass of the Moon. page 6
