WASHINGTON (WUSA9) -- This weekend, you'll see a super-sized moon in the sky. The full moon will make its closest approach to the Earth during its orbit (perigee), making it look bigger than usual.

On Friday, NASA scientist Noah Petro joined WUSA9 Meteorologist Erica Grow to talk about the "supermoon."
