Leonid Meteor Shower 2019: When, Where & How to See It

Next week, the fickle Leonid meteor shower hits Earth once again. This annual meteor shower, which peaks overnight on Nov 16-17, is responsible for some of the most intense meteor storms in history. Sometimes, meteors fall at rates as high as 50,000 per hour.

These storms only happen rarely; viewers this year will see few meteors outshined by a bright moon. The best time to look in past years was before dawn around 3 a.m. EST (0800 GMT) on the night of the peak, according to Jane Houston Jones of NASA's Jet Propulsion Laboratory.

When to see them

The Leonid meteor shower peaks on the night of Sunday, Nov. 17, and early the following morning. Skywatchers may be able to see some meteors on days just before and after the peak, although the moon will continue to obstruct views. According to NASA meteor expert Bill Cooke, without moonlight skywatchers would have been able to see around 10-15 meteors per hour during the peak. [Most Amazing Leonid Meteor Shower Photos]


Where to see the Leonids

The Leonid meteor shower gets its name from the constellation Leo, where its meteors appear to originate. But you can look in just about any direction to enjoy the show, Cooke said. If you directly face Leo, you may miss the meteors with longer tails.

Although the meteor shower might be a bit easier to see from the Northern Hemisphere, skywatchers in the Southern Hemisphere should be able to see the show as well. "They're not quite as good, but almost as good," said Cooke. "The Leonids are an OK shower from the Southern Hemisphere."

What causes the Leonids?

The Leonid meteor shower happens every year in November, when Earth's orbit crosses the orbit of Comet Tempel-Tuttle. The comet makes its way around the sun every 33.3 years, leaving a trail of dust rubble in its wake.

When Earth's orbit crosses this trail of debris, pieces of the comet fall toward the planet's surface. Drag, or air resistance, in Earth's atmosphere cause the comet's crumbs to heat up and ignite into burning balls of fire called meteors. [How Comets Cause Meteor Showers]

These comet crumbs are usually the size of a grain of sand or a pea, so they tend to burn up entirely before striking Earth's surface. Meteors that survive the whole journey to the ground are called meteorites. But the Leonid meteor shower likely won't deliver any meteorites.

What do you need to see them?

Meteors are visible to the naked eye, so you won't need any special equipment to see them. 

"Go outside, find a dark sky, lie flat on your back and look straight up," Cooke said, "and be prepared to spend a couple of hours outside."

Given that the meteors are fairly sparse and take place during a cold time of year, it is best to bundle up and relax.
