The three-digit designation for the Perseid meteor shower in the 2026 meteor-shower list is 007.
Meteor showers receive standardized identifiers so astronomers can distinguish them in observing reports, catalogs, and databases. The Perseids also have the three-letter code PER, but that code is different from the shower’s numerical designation.
The 2026 list places the Perseids among the major annual showers, alongside entries such as the Quadrantids, Lyrids, Orionids, Leonids, and Geminids. Its row also gives the shower’s dates, peak date, radiant coordinates, entry speed, expected ZHR, rating, and parent body.
The number 007 identifies the Perseid shower itself, not Comet 109P/Swift–Tuttle. The comet is the parent body associated with the stream, while 007 is the meteor-shower catalog number. Keeping those identifiers separate prevents a common mix-up between a shower designation and a comet designation.
