Geminid meteor shower peaks tonight; Comet Wirtanen may add sparks

Earthlings will have a good chance of witnessing shooting stars between sunset Thursday and sunrise Friday, courtesy of the Geminid meteor shower.

Dozens of bright objects will streak across the sky each hour between dusk and dawn as the annual Geminid show reaches its peak, according to the editors of StarDate magazine at the McDonald Observatory at the University of Texas in Austin. This year’s display will not be impeded by light from the moon, since it will set shortly after the sun does. (Southern Californians may be out of luck though, as weather forecasters are predicting a roughly 40% to 50% chance of cloud cover overnight.)

Despite their bright, twinkly appearance, the objects that will be on display are not actually stars – they’re remnants of the asteroid Phaethon that burn up when they hit the Earth’s atmosphere. Our planet orbits through Phaethon’s debris field at this time every year. Most meteor showers are the result of Earth's passing through the remnants of a comet, but the Geminid meteor shower was the first to be traced to an asteroid, according to StarDate.

The meteor shower gets its name from the constellation Gemini, since the objects seem to fall near one of its primary stars, Castor. You can get some help locating the constellation, which is northeast of Orion, from Space.com.

As a bonus, the Geminid meteor shower may get a boost from dust left behind by Comet Wirtanen, according to NASA. Bill Cooke of the space agency’s Meteoroid Environment Office predicted that the dust could create up to 30 additional meteors per hour.

According to this explainer from NASA, Comet Wirtanen has not crossed paths with Earth since it was discovered in 1948. But Russian forecaster Mikhail Maslov has run computer models that indicate our planet could cross the comet’s debris stream as many as four times between now and Friday.

If Comet Wirtanen does produce meteors, sky watchers will be able to distinguish them from Geminid meteors because the meteors from the comet will appear to emanate from the constellation Pisces, according to Earthsky. The Clark Foundation offers this advice for finding Pisces in the sky.

The farther you can get from city lights, the better your view, of course. For more advice on watching the Geminid meteor shower, check out these 10 tips from EarthSky.

Thanks Al, and for once I'm not kidding. It looks like the sky is going to be bell clear tonight.

I think I'll take a nap later,then drive to the farm to watch the show about 2 am.

Remember to look *UP*, and, if it starts to rain, don't keep your mouth open.

Meteor hunting on Dec. 13-14 is a no-lose proposition because, as Cooke points out, even if the new shower is a dud, the Geminids should be great. With no glaring Moon to spoil the show, observers in rural areas should be able to see as many as 120 Geminid meteors every hour. The best time to look is during the dark hours before sunrise on Friday, Dec. 14th.

Thanks for the tip,I didn't know about the rain thing.

One of my Uncle's friends claimed he got his tonsils and throat sunburned when they were in the Navy. It happened just a couple of days after the guy accidently walked into a hotel room that wasn't his in the pitch dark. Luckily,he fell face first between the thighs of a young Philippina who worked in the bar downstairs,and wasn't hurt.

The moral is,if you're ever in the Phillipines,don't walk into a hotel room that's not yours. You might get your tonsils sunburned.
