See highlights from the Dec. 2017 supermoon all over the world.

A supermoon means the full moon looks bigger and brighter than normal.

Of course, the moon doesn't actually change size, but it appears to be larger because of how its orbit lines up with the Earth and sun.

If you missed it -- no worries.

The first two full moons of 2018 will also be supermoons.

ABC7 viewers went outside to catch a glimpse of the supermoon and shared incredible photos using #abc7eyewitness.
