You know that super moon the other night? How could that happen?
Madame L is glad you were able to see that!
As you already know, the moon's orbit around the earth isn't exactly like a circle, more like a big oval or ellipse. So sometimes it's closer to us than other times, and when it's really close and also a full moon, that's when we see the super moon.
Here's a NASA scientist being interviewed about it. She explains why even at its closest the distance from the moon to us is different at different times of the year. Madame L learned a lot by watching this video, and she thinks you'll enjoy it, too.
This time, the moon was just over 220,000 miles from the Earth (about 357,000 kilometers) at its perigee last Sunday morning, June 23. The next time the moon will be that close will be in August 2014.
