Why Does the Moon Go Around the Earth?

Almost everything in the universe travels in a circular path. The moon goes around the earth, the earth goes around the sun, and even the sun revolves around the center of our galaxy. This is because of two basic laws of science.

First, an object moving in space, where there is no air to slow it down, will continue to move forever once it begins in motion. The moon has been moving through space ever since it was formed billions of years ago.

But the gravity of the earth pulls the moon toward us. This gravity isn’t strong enough to pull the moon into the earth, but it holds the moon at a certain distance from the earth, where the gravity of the earth, the sun, and the planets are balanced.

So the moon keeps moving around the earth at that distance, traveling in a circular path called an orbit. And the earth goes around the sun for the same reason.

  1. The moon isn’t held in that position, in fact modern theories state that the moon was much closer to the Earth and is moving farther away and an extremely slow rate. So there really isn’t any certain distance the moon will constantly be at.

  2. Earth has gravity and tries to pull the Moon. Moon in turn has gravity and tries to pull the Earth. Due to the pulling in opposite directions the present status quo is maintained. Now, Earth moves around its axis. Due to this the lines of attraction between Earth and Moon is broken. This causes the Moon to revolve around the Earth. As the force of attraction is always constant, the path of Moon is circular. We can imagine Earth and Moon as Giant magnets and we know that we can move one magnet using another without physical contact.Thus we can conclude the reason for Moon revolution around Earth is the action of Earth’s rotation on its axis.
