Geminid Meteors over Xinglong Observatory.

Where do Geminid meteors come from? In terms of location on the sky, as the featured image composite beautifully demonstrates, the sand-sized bits of rock that create the streaks of the Geminids meteor shower appear to flow out from the constellation of Gemini . In terms of parent body, Solar System trajectories point to the asteroid 3200 Phaethon -- but this results in a bit of a mystery since that unusual object appears mostly dormant . Perhaps, 3200 Phaethon undergoes greater dust-liberating events than we know . Over 50 meteors including a bright fireball were captured during the peak of the 2015 Geminids Meteor Shower streaking above Xinglong Observatory in China . The Geminids of December are one of the most predictable and active meteor showers . This year's Geminids peak tonight and should be particularly good because, in part, the nearly new Moon will only rise toward dawn and so not brighten the sky.
