- Geminids
The Geminids are a
meteor shower caused by an object named3200 Phaethon , which is thought to be an extinctcomet . The meteors from this shower can be seen in mid-December and usually peak around 12-14 of the month. The Geminid shower is thought to be intensifying every year and recent showers have seen 120-160 meteors per hour under optimal conditions. The Geminids were first observed only 150 years ago, much more recently than other showers such as thePerseids andLeonids .Radiant
The meteors in this shower appear to come from a radiant in the constellation Gemini (hence the shower's name). However, they can appear almost anywhere in the night sky, and often appear yellowish in hue. The meteors travel at medium speed in relation to other showers, at about 22 miles per second, making them fairly easy to spot. The Geminids are now considered by many to be the most consistent and active annual shower. In
2005 , viewing of the shower was restricted due to afull moon washing out the fainter meteors. The2006 shower had a less full moon, however the2007 shower was a new moon, with the best viewing position being in the southern hemisphere, withAustralia andNew Zealand being noted spectacle locales.See also
