PHOENIX (ARIZONA'S WEATHER AUTHORITY) -- It will be easy to remember when the full moon will take place this month. It will be at its fullest at 12:12 a.m. Eastern time on 12/12, and it will be the last full moon of the decade.

Native Americans made a calendar of full moons, naming each one. They called the December moon the "Full Cold Moon" to recognize the long, cold winter nights ahead. The winter solstice, which is on Dec. 21 this year, is the longest night of the year.

The next event for stargazers will be the Geminid meteor shower, which peaks this weekend. This is the most popular meteor shower to see; it can bring up to 120 meteors per hour. The "Full Cold Moon" will still be about 85% full, so it could hamper viewing this year.

The peak of the meteor shower will be late Saturday evening. For the best views, experts say to head to the desert outside the city to avoid the city lights.
