There was a full moon Saturday night, but not just any old full moon.
This moon was bigger and brighter. In fact, the moon appeared to be 14% bigger, and 30% brighter.
This phenomenon is called a Supermoon. The moon looked this way because it was just 211,565 miles away from the earth. That's the closest its been since March of 1993.
The moon's closer-than-normal proximity can cause slightly higher tide levels. However, astronomers have discredited the internet rumor that this supermoon occurence had anything to do with the recent tsunami in Japan.
