(WHAS11) -- The moon was at its closest point to Earth at the time it turned full Saturday night. This made it appear 14 percent larger and 30 percent brighter than a normal full moon.
According to NASA, the scientific term for the phenomenon is "perigee moon." Full Moons vary in size because of the oval shape of the Moon's orbit. The Moon follows an elliptical path around Earth with one side ("perigee") about 50,000 km closer than the other ("apogee"). Full Moons that occur on the perigee side of the Moon's orbit seem extra big and bright.
The last super moon was on March 19, 2011.
