The Geminid meteor shower peaks tonight into Monday morning. If you have a chance, you should really check them out. It’s best to have a western view, and they tend to peak between midnight and 2:00 am.
Their name derives from the fact that they seem to come from the direction of Gemini. Like other meteor showers, the Geminids are the debris trail of a comet. In this case a rock comet known as Phaethon. Phaethon is more asteroid-like than comet-like in many ways, and as a result the Geminids are consistently good meteor showers.
