As you read through this article you learn that the moon does not orbit around the Earth on the same plane. Because of its path, the moon has either an ascending or descending orbit every two weeks or 28 days as it revolves around the Earth. When the orbit of the moon and the Earth intersect we call that a node. This all leads to the fact that we don’t have two eclipses a month. Even more information is contained in the article as the reader learns about regression of nodes. All these terms help the reader understand the motion of celestial bodies in our solar system.
