			The highest tides, '''spring tides''', occur during full and new moons, since the Moon and the Sun both pull on the oceans. High tides, pulled mostly by the Moon alone, are called '''neap tides'''.

			Even though the mass of the Moon is relatively small, and only has a sixth the gravity of Earth, the Moon has more influence over the tides than the Sun, because the Sun is vastly further away.

	The oceans nearest the Moon are pulled more than the center of the Earth, which is pulled more than the oceans on the far side. With respect to the center of the Earth, it is as if oceans are pulled in opposite directions. As the Earth rotates under the ocean's bulge, it experiences two tides each day. The height of the tide depends upon the position of the Moon relative to the Sun.

	Since the composition of the Moon is similar to the Earth, except it lacks any iron core, present theory is that it was blasted off the surface of the Earth by a giant asteroid. The Earth would have still been in a molten state then, but the iron would mostly have sunk to Earth's core. The debris of the collision reassembled around the Earth to make the Moon. Simulations of potential impacts have identified that an one capable of forming an Earth-Moon system is of Earth at the end of its formation with Mars-sized object, about 4.5 billion years ago.
