The moon will appear slightly larger and brighter Monday night during what's known as a supermoon. October's supermoon is the first of three this year. It happens when a full moon is closer to Earth in its orbit. That makes the moon look up to 14% bigger and 30% brighter than the faintest moon of the year, according to NASA. The subtle difference happens a few times a year, sometimes coinciding with other astronomical events such as lunar eclipses.
