Шаблон:Use dmy dates Шаблон:Infobox meteor shower Alpha Capricornids is a meteor shower that takes place as early as 7 July and continues until around 15 August.[1] The meteor shower was discovered by Hungarian astronomer Miklos von Konkoly-Thege in 1871.[2] This shower has infrequent but relatively bright meteors, with some fireballs. Parent body is comet 169P/NEAT.

Peter Jenniskens and Jeremie Vaubaillon identified the parent body as asteroid 2002 EX12, which in the return of 2005 was found weakly active near perihelion.[3] This object is now called comet 169P/NEAT.

According to Jenniskens and Vaubaillon, the meteor shower was created about 3,500 to 5,000 years ago, when about half of the parent body disintegrated and fell into dust.[3] The dust cloud evolved into Earth's orbit recently, causing a shower with peak rates of 2-5/h, sometimes having outbursts of bright flaring meteors with rates up to 5-9/h.

The bulk of the dust will not be in Earth's path until the 24th century. The Alpha Capricornids are expected to become a major annual storm in 22202420 A.D., one that will be "stronger than any current annual shower."[3]
