See the 2017 Leonid Meteor Shower at Its Peak: What to Expect

The famous Leonid meteor shower is predicted to reach its peak in the predawn hours on Friday (Nov. 17). Weather permitting, observing conditions will be perfect: There's a new moon on Saturday, which means that the sky will be dark with no hindrance whatsoever from moonlight.
But don't expect to see a lot of meteors. In fact, a single observer will likely see no more than 10 to 15 of these meteors per hour emanating from the "sickle" of Leo, the lion.
Hence the moniker for these meteors: the "Leonids." The sickle a star pattern that looks like a backward question mark and outlines the "mane" of Leo the lion rises above the east-northeast horizon around 11 p.m. local time. By about 5 a.m. local time, this eye-catching star pattern will have ascended to a position high in the south-southeast part of the sky. [Most Amazing Leonid Meteor Shower Photos]
The Leonid meteor shower is an extremely variable event that happens every year when Earth's orbit crosses a trail of comet crumbs left behind by Comet Tempel-Tuttle. A dense swarm of Leonid meteors returns to Earth about every 33 years, or about the time it takes for Tempel-Tuttle to orbit the sun.
