The super “pink” moon will rise on April 7. A supermoon occurs when a full moon happens on the same night the moon reaches perigee. Perigee is when the moon is closest in its orbit to the Earth. Even though it is called the super pink moon the moon will not change color. Supermoons are only about 15 percent brighter and 7 percent bigger. The change in size happens because of the eccentric orbit. The orbit is not perfectly circular. The moon gets closet to the earth in its orbit that is what creates the appearance that the moon is bigger than normal.
