A supermoon rises behind the Washington Monument in the nation's capital on June 23, 2013. The "supermoon" is so named because it's the biggest, brightest full moon of the year. The supermoon's disk is 14 percent wider and 30 percent brighter than the moon's minimum appearance. This is the result of the moon going full at roughly the same time that it reaches perigee - its closest point to Earth in the course of its orbit.
