Annual Visitors
The Perseid meteor shower comes every year, usually in late July. Sky watchers outdoors at the right time can see colorful fireballs, occasional outbursts and, almost always, long hours of gracefully streaking meteors. The source of the shower is Comet Swift-Tuttle. Tiny bits of comet dust hit Earth's atmosphere traveling 132,000 mph. At that speed, even a tiny smidgen of dust makes a vivid streak of light when it disintegrates.
