The Perseids, the year's most popular meteor shower, will peak tonight, but August's waning full moon could impact viewing. Here's what to know.

The Perseids are peaking tonight and Tuesday with mostly clear skies on tap. But will haze and a somewhat full moon play spoiler?

The Perseids are known for being especially swift and bright, and in a good year viewers can expect to spot between 50 and 100 meteors in an hour. This year, with moonlight hampering dark skies, fewer than half the usual number of meteors could be visible. Still, 25 shooting stars an hour is worth waking up early for.
