Geminids

A major annual meteor shower, the radiant of which lies near the star Castor in the constellation Gemini. The shower peaks around 13 December, and the normal limits are 7-16 December. The meteor stream has an unusual orbit with a perihelion distance of only 0.14 AU. IRAS, the Infrared Astronomical Satellite, discovered a cometary nucleus in 1983, designated as asteroid 3200 Phaethon, which appears to be the parent body for this stream.
