Meteor experts say the Geminid meteor shower is hands-down the best in the heavens, producing 120 multicolored meteors at the peak. The moon is not a factor this year. Produced by debris left behind by an asteroid known as 3200 Phaethon, which was discovered in 1982. This shower runs from Dec 7-17. It peaks this year on the night of the 13th and morning of the 14th. Meteors will radiate from the constellation Gemini, but can appear anywhere in the sky.
