The gravitational pull of the Moon on the Earth is about 2.0 x 1020 newtons, while the pull of the Sun on the Earth is about 3.5 x 1022 newtons.
(Note that the reason the Sun doesn't affect tides on earth as strongly as the moon--roughly 1/3 the effect--is that, while it's gravitational pull is much stronger than that of the moon, the differential force is smaller because it's so far away.
