Perseids on August 12, 2007 from NASA.


Perseids are the repeatedly left behind debris from the periodic comet 109P/Swift-Tuttle.

109P/Swift-Tuttle has an orbital period of 133.28 years and was last around in 1992. Its next trip to the Sun, perihelion, will be in 2126. It has an perihelion distance of 0.96 AU (i.e., just inside Earth’s orbit) and an aphelion of 51.2 AU — which takes it past Pluto.

The name, as explained in the post referenced above, comes from the constellation Perseus — where the meteors appear to originate.
