Geminids stand apart from the other meteor showers in that they seem to have been spawned not by a comet, but by 3200 Phaethon, an Earth-crossing asteroid.
The Geminids may be comet debris, for some astronomers consider Phaethon to really be the dead nucleus of a burned-out comet that somehow got trapped into an unusually tight orbit.
The Geminids are predicted to reach peak activity on Dec. 14 at 16:45 GMT (11:45 a.m. ET). That means those places from central Asia eastward across the Pacific Ocean to Alaska are in the best position to catch the very crest of the shower, when the rates conceivably could exceed 120 per hour.
The Geminids begin to appear noticeably more numerous in the hours after 10 p.m. local time, because the shower's radiant is already fairly high in the eastern sky by then.
The best views come around 2 a.m. local time, when their radiant point will be passing very nearly overhead.
