The night sky on May 5 was animated by
the once-a-year cosmic event of the perigee moon. Popularly known as
the "Supermoon", the moon appears much larger above us when the
elliptical orbit brings it within 221,802 miles to Earth, the closest
point. The effect is magnified during a full moon, when we see our
nearest celestial neighbor appear roughly 20 percent brighter and 15
percent larger.
