The Moon follows an elliptic orbit around Earth. Naturally, sometimes it gets closer to the Earth than the other times. When it’s also full moon at its closest point to the Earth, it’s called Supermoon. As a result, the moon appears larger and brighter than usual in the sky.

The counterpart of a supermoon is called micromoon. A Supermoon looks around 12% to 14% bigger (in diameter) than the Micromoon.
