text: On the evening of Tuesday, November 17, and into the morning of Wednesday, November 18, the Leonid meteor shower will hit its peak. The annual event, caused by bits of ice and rock burning in Earth’s atmosphere, will create a host of shooting stars above the eastern horizon around midnight in the U.S. (local time on both coasts, when the constellation Leo rises). Here’s our guide to the shower. Where To Look, And When Any single meteor might appear anywhere, but for the most part Tuesday’s shooting stars will appear to come from the constellation Leo—hence, “Leonids.” Leo will rise above the eastern horizon at about midnight local time across the continent. But meteors will be visible even before then. So if you're in the U.S. and the skies are clear, head out any time after sunset on Tuesday, November 17, and look east. Try to find a dark site away from street lights, or better yet, away from cities altogether. 
   
   Leo, the apparent origin point for the meteors, rises in the east at midnight. That’s the direction to look to maximize the chance of spotting a shooting star Tuesday night.

   Likely Awesomeness Rating: Medium The Leonids peak every three decades, and this shower comes mid-cycle—the last peak was in 1998. So we won’t see a phenomenal number of shooting stars. (If you’re bummed about that, console yourself with some of the illustrations of the famous 1833 Leonid meteor storm—a pretty incredible event.) This year, NASA predicts we’ll see one meteor about every four minutes. That’s a moderate rate. But in this year’s favor, the moon will be a crescent, which means a darker sky that makes streaks of light easier to spot. Strike against: the current cloud-cover forecast predicts overcast skies for a good fraction of the U.S. that night. Why Now? The Leonids happen every year around November 17. That’s when the Earth passes through the cloud of debris left behind by the comet Tempel-Tuttle. Don’t worry about an actual impact—Tempel-Tuttle is currently further than Uranus. We’re just crossing its orbit. There’s no chance we’ll hit the comet itself. 
   
   The Leonid meteor shower happens in November each year because that’s when the Earth, moseying along its orbit, passes through the debris field of the comet Tempel-Tuttle.

target: – Get ready to tune your eyes on the sky: The annual Leonid meteor shower will hit its peak overnight on Tuesday, sending shooting stars above the eastern horizon around midnight local time on both coasts. Unfortunately, clouds will cover much of the skies across the US, but those in areas with a clear forecast will enjoy a dark backdrop for the colorful meteors thanks to a crescent moon. NASA predicts there will be about 15 meteors per hour, or one every four minutes, at peak time. If you can't make it until midnight, some meteors will also be visible to the east after sunset, reports Popular Science.
