Don't let this year's last supermoon pass you by –– especially since you'll have to wait nearly a year for the next one.
A supermoon is a new or full moon that's at its closest to Earth.
The sixth this year is the night of Oct. 26 into the morning.
The fifth was an ultra-rare blood moon eclipse.

Each year, we expect four to six supermoons, but only a few coincide with full moons.
If you miss this week's show, you won't be able to see another full moon supermoon until next October.
