The Geminid Meteor shower occurs each December, and this year we can expect to see up to 50 meteors each hour. Check out this awesome timelapse that I wish I could say I did, but someone else made it…. This timelapse was taken of the Geminids last year over the Pacific Coast.
Meteor showers are caused when Earth passes through the orbital path of a comet, the debris left behind by the comet falls into Earth’s atmosphere creating many shooting stars. The Geminid shower is different. Scientists have determined that this shower occurs when Earth passes through a debris field of an asteroid. This asteroid is called 3200 Phaethon. Observations show that this object is strange indeed, and sometimes behaves similar to a comet. Its orbit brings it in close to the Sun, and then back out again. Jets of dust and gas have been seen spewing from the asteroid at times. Tiny pieces of dust and rock are left behind by 3200 Phaethon as it travels through space, and these cause the Geminid Meteor Shower. The tiny arrows in the image below point to 3200 Phaethon, this image was created by combining multiple images over the span of 20 minutes to show the asteroid’s movement relative to the background stars.
Meteor showers are named for constellation that their radiant lies in. The radiant is the point from which the meteors appear to radiate from in the sky. The constellation Gemini will rise above the horizon around 9 PM Central Time tonight (December 13th). It will be nearly overhead around 2 AM. This year the moon will also be visible in the sky, which will make it more difficult to see the fainter meteors.
While Baton Rouge forecasts are saying rain throughout this evening, some reports indicate that the sky will clear a bit after midnight. Incidentally this is the best time to go out and find meteors! Meteor watching requires patience and sharp eyes, each year the number of meteors changes. Happy viewing!
