Perigee

I hope you noticed that the moon was exceptionally bright on Friday night. It is what you call a perigee (per'i je). This is the point in the orbit of a heavenly body such as the moon or even an artificial satellite at which it is the closest to the earth. That night it was about 30% brighter. It was so amazing. This can happen once or twice a year when the moon is full. Just thought you would want to know why it was so bright and beautiful.
