Predicted peak: August 13, 2022, at 3 UTC.
When to watch: The moon will be up all night during 2022’s predicted* peak of the Perseid meteor shower. But this shower rises to a peak gradually, then falls off rapidly. And Perseid meteors tend to strengthen in number as late night deepens into the wee hours. The shower is often best before dawn. So, in 2022, from early August to mid-August, watch from late evening to dawn, until the waxing moon – brighter each night, and up for more hours – drives you back inside.
Duration of shower: July 14 to September 1.
Radiant: The radiant rises in the middle of the night and is highest at dawn. See chart below.
Nearest moon phase: Full moon falls at 1:36 UTC on August 12. There will be a bright moon up during the Perseids’ peak in 2022. Take advantage of the moon-free mornings in late July and early August for watching the Perseids (and the Delta Aquariids).
Expected meteors at peak, under ideal conditions: Under a dark sky with no moon, skywatchers frequently report 90 meteors or more per hour.
Note: The August Perseid meteor shower is rich and steady, from early August through the peak. The meteors are colorful. And they frequently leave persistent trains. All of these factors make the Perseid shower perhaps the most beloved meteor shower for the Northern Hemisphere.
The annual Perseids meteor shower radiant rises late in the evening, around 11 p.m. local time, nearly due northeast in the constellation Perseus. Perseids are best viewed from midnight to sunrise, but moonlight will outshine dim meteors all night in 2022. The greatest number of meteors will be visible after the radiant rises, but the shooting stars themselves can appear anywhere in the sky, seeming to trail from the radiant point.
The beloved Perseid meteor shower
In the Northern Hemisphere, we rank the August Perseids as our all-time favorite meteor shower. The Perseids take place during the lazy, hazy days of northern summer, when many families are on vacation. And what could be more luxurious than taking a siesta from the heat of the day and watching this summertime classic in the cool of night? No matter where you live worldwide, the Perseid meteor shower will probably produce the greatest number of meteors on the mornings of August 11, 12 and 13.
Perseid meteor shower radiant point
If you trace all the Perseid meteors backward, they seem to come from the constellation Perseus, near the famous Double Cluster. Hence, the meteor shower is named in honor of the constellation Perseus the Hero..
If our planet happens to pass through an unusually dense clump of meteoroids – comet rubble – we’ll see an elevated number of meteors. We can always hope!
Comet Swift-Tuttle has a very eccentric – oblong – orbit that takes this comet outside the orbit of Pluto when farthest from the sun, and inside the Earth’s orbit when closest to the sun. It orbits the sun in a period of about 133 years. Every time this comet passes through the inner solar system, the sun warms and softens up the ices in the comet, causing it to release fresh cometary material into its orbital stream.
Comet Swift-Tuttle last reached perihelion – closest point to the sun – in December 1992 and will do so next in July 2126.
Bottom line: The 2022 Perseid meteor shower should produce the most meteors in the predawn hours of August 11, 12 and 13, but many faint meteors will be outshone by an almost full moon. Here’s how to get the most from this year’s shower.
