If Earth travels through this stream, we will see a meteor shower.
Although the meteors can appear anywhere in the sky, if you trace their paths, the meteors in each shower appear to "rain" into the sky from the same region. Meteor showers are named for the constellation that coincides with this region in the sky, a spot known as the radiant. For instance, the radiant for the Leonid meteor shower is in the constellation Leo.

The Perseid meteor shower is so named because meteors appear to fall from a point in the constellation Perseus. Traveling at tens of thousands of miles an hour, meteoroids quickly ignite from the searing friction with the atmosphere, 30 to 80 miles above the ground. Almost all are destroyed in this process; the rare few that survive and hit the ground are known as meteorites. When a meteor appears, it seems to "shoot" quickly across the sky, and its small size and intense brightness might make you think it is a star.
If you're lucky enough to spot a meteorite a meteor that makes it all the way to the ground , and see where it hits, it's easy to think you just saw a star "fall.
Get away from the glow of city lights and toward the constellation from which the meteors will appear to radiate. For example, drive north to view the Leonids. Driving south may lead you to darker skies, but the glow will dominate the northern horizon, where Leo rises. Perseid meteors will appear to "rain" into the atmosphere from the constellation Perseus, which rises in the northeast around 11 p. After you've escaped the city glow, find a dark, secluded spot where oncoming car headlights will not periodically ruin your sensitive night vision.
The display lasts for a couple of weeks, but this year it peaks on May 6. It's probably not worth bothering driving a dark sky location, but May 6, and a few evening either side, is perfect for stargazing. Even if you don't see many shooting stars, you will see the Milky Way.
Those in the southern hemisphere get the best view for this one, but don't stress about it if you're in the north. Those in the northern hemisphere will also see shooting stars, though it pays to look generally south since the constellation of Aquarius is very low, and even under, the southern horizon.
