On Sunday night the moon will be full while at its closest point in its orbit to the Earth, called its perigee.
This occurrence has taken on the name "supermoon".
This will be the closest the moon will be to the Earth this year... so maybe it should be called the "super supermoon."
The moon will appear bigger and brighter than your average full moon, and the weather should be great for lots of pictures.
It will also happen again September 9.

The one this weekend will likely be the brightest.
However, scientists stress that sometimes it's hard to tell the difference between a supermoon and a regular full moon, as clouds and haze can mask a difference in brightness.
The only bummer will be that the brightness of the moon will make it more difficult to see the Perseid meteor shower, which will peak from the 11th through the 13th.
