Tonight we will have a full moon. But it's not just any full moon. The full moon has two special characteristics. It's technically happening just after midnight - on Friday the 13th. The full moon is also what astronomers call a Super Moon.. The full moon on Friday the 13th is a rarity. According to David DeBruyn, emeritus director for the Chaffee Planetarium in Grand Rapids, a full moon on Friday the 13th hasn't happened since October 2000. He also says the next full moon on Friday the 13th won't occur until August 2049.
we will see a full moon every time when the sun, the earth, and the moon are lined up in that order. And this happens once while the moon travels around the earth. And one turn of the moon around the earth takes about a month. Thus we have one full moon per month and 12 full moons per year. The full moon last only for one day because the moon travels on constantly. And we can predict the time point for full moon exactly by the second, because the moons orbit around the earth is known exactly. Bye
