The Geminids — among the few major meteor showers to come from asteroids — peak on Friday. It's one of the year's last chances to see fireballs in the sky.

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

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.
