Dazzling Geminid meteor shower to light up the holiday season: How, when to watch

11:27 a.m. Monday, Nov. 6, 2017 National/World News

The holiday season is about to get a lot brighter this year with the famous Geminid meteor shower sparkling the night sky.

If  you plan to catch a ride aboard the train at Macy’s Pink Pig in Atlanta — a local holiday tradition — or attend one of the most spirited holiday parades in the country, you may also want to squeeze in some time for this celestial spectacle in December.

Here’s what you need to know about the 2017 Geminid meteor shower: 

VALLEY OF FIRE STATE PARK, NV - DECEMBER 14: A Geminid meteor streaks diagonally across the sky against a field of star trails over one of the peaks of the Seven Sisters rock formation early December 14, 2007 in the Valley of Fire State Park in Nevada. The meteor display, known as the Geminid meteor shower because it appears to radiate from near the star Castor in the constellation Gemini, is thought to be the result of debris cast off from an asteroid-like object called 3200 Phaethon.

Though the Geminids were washed out by the supermoon last year, the bright display known as one of the best annual meteor showers, will return and peak during mid-December this year.

While most meteor showers originate from comets, the Geminids originate from the asteroid 3200 Phaethon, which takes 1.4 years to orbit the sun, according to NASA.

“It is possible that Phaethon is a ‘dead comet’ or a new kind of object being discussed by astronomers called a ‘rock comet,’” NASA reported. But because Phaethon doesn’t develop a cometary tail as it passes the sun and its meteoroids are much denser than cometary debris, scientists aren’t exactly sure how to define Phaethon. 

The 3.17-mile asteroid was discovered in 1983 by the Infrared Astronomical Satellite.

The Geminid meteors are named after their radiant, defined as the point in the sky from which they appear to come from, the constellation Gemini.

Bill Cooke, head of NASA’s Meteoroid Environment Office told Space.com that a meteoroid is essentially space debris. For example, the “crumbs” left behind from Halley’s Comet trail are meteoroids.

These “crumbs” can also be left behind by asteroids, such as the 3200 Phaethon.

Once the meteoroids enter Earth’s atmosphere, they become meteors (or shooting stars).

Though most meteors disintegrate before hitting the ground, meteors that do strike the surface of the planet are called meteorites, Cooke said.

The Geminid meteor shower will begin to be visible on Dec. 7 and last through about Dec. 17.

This year, it will peak around 2 a.m. on the night of Dec. 13 and morning of Dec. 14.

According to NASA, the shower starts around 9 or 10 p.m.

The Geminids will travel at about 22 miles per second.

You could see meteors speed across the dark sky at rates as high as 120 meteors an hour.

The meteor shower will be visible from anywhere on the planet, but be sure to go somewhere far from city lights.

According to Space.com, binoculars and telescopes won’t actually help. That’s because those tools are designed to magnify and focus on stationary objects in the sky.

The naked eye will do just fine.

When you’re outside in the dark, lie flat on your back with your feet facing south and look up at the vast sky.

Give yourself 30 minutes for your eyes to adapt to the environment.

Be sure to being warm clothing, a sleeping bag, blanket or lawn chair.

Though you can view the Geminid meteor shower throughout the night sky, stargazers may be interested in identifying the meteors’ radiant, the constellation Gemini.

One of the best ways to find Gemini is to look for the constellation Orion first, easily identifyable by the naked eye thanks to its three bright stars in the hunter’s “belt.” You’ll be able to see Gemini’s two brightest stars, Castor and Pollux, always sitting noticeably close to each other in the sky.

If you’re having trouble identifying the constellations, consider downloading some sky-watching apps, such as SkyView Free (on Android and iOS) or Sky Map (Android).

GLOBE at Night also has a nifty Orion Finder Chart that will show you Orion based on your location, for anyone interested.

The easiest way to find Orion is to go outside in the evening and look in the southwest sky if you are in the northern hemisphere or the northwestern sky if you are in the southern hemisphere. If you live on or near the equator, he will be visible in the western sky. You are looking for three bright stars close together in an almost-straight line. These three stars represent Orion's belt. The two bright stars to the north are his shoulders and the two to the south are his feet. 

“For best results, you should look slightly away from Gemini so that you can see meteors with longer ‘tails’ as they streak by; staring directly at Gemini will just show you meteors that don't travel very far,” Space.com reported.
