There are three meteor showers left this year. Geminids will peak Dec. 13 and 14, producing up to 150 meteors per hour.

Under ideal viewing conditions, the Geminids typically put on one of the best and brightest shows of the year because of the high volume of meteors visible each hour. However, an almost full moon this year means up to 15 meteors per hour are expected at peak time, according to the American Meteor Society.

The year's most reliable meteor shower is happening, but the best time to watch will be when it peaks Friday and Saturday nights. Here's how to watch.
