Perseid Meteor Shower Returns, Expected to Peak in Mid-August

The Perseid meteor shower, a prominent annual astronomical event, is active from July 17 through August 23 this year. The shower is expected to reach its peak on the night of August 12 into the early hours of August 13, when skywatchers could observe more than 50 meteors per hour, and potentially up to 75, depending on viewing conditions. However, the full sturgeon moon on August 9 may reduce visibility during the peak period.

The Perseids originate from debris left by comet 109P/Swift-Tuttle, which has the largest nucleus among comets that regularly approach Earth. The comet completes an orbit around the sun every 133 years, and its connection to the meteor shower was first identified in 1865. The meteors appear to radiate from the constellation Perseus, though their true source is the comet's debris.

According to Bill Cooke of NASA, the Perseids are notable for producing larger particles than many other meteor showers, resulting in "bright fireballs" that are easier to spot in the night sky.

Other meteor showers are also active during this period. The Alpha Capricornids, recognized for their vivid bursts, and the Delta Aquariids, which can produce 10 to 20 meteors per hour, will both peak on the night of July 29-30.
