The full Moon of August 10th was as much as 14% bigger and 30% brighter than other full Moons of the year
Vesa Vauhkonen of Rautalampi, Finland: “I compared the normal full Moon of March 2014 with the Supermoon of Aug 2014,” says Vauhkonen. “In individual images, the difference in size might be difficult to see, but putting them side by side makes the difference clear. I used the same photo settings for both images, so the scaling has no errors.”
Supermoons are possible because the Moon’s orbit is not a circle, it is an ellipse. One side, perigee, is 50,000 km closer than the other, apogee. On August 10th the Moon became full just as it reached perigee, the point closest to Earth. This caused the Moon to appear authentically bigger and brighter than usual.
