In the early morning hours of Aug. 4, the waning crescent moon will lie near the Pleiades, or the Seven Sisters. In August the full moon will be the smallest of the year, as it is at apogee at 252,518 miles, its most distant point in its orbit when full.

The parent comet of the Perseid shower, is Comet Swift Tuttle, discovered by joint observers. Astronomer Lewis Swift discovered the comet on July 16, 1862, and Astronomer Horace Tuttle on July 19, 1862.
The comet has an official designation as 109P/Swift Tuttle ... this being the 109th periodic comet discovered. The comet orbits the sun with a period of some 130 years and may be an object of concern for future generations.
Comet Swift/Tuttle may be the single most "dangerous" object known to mankind, as it is the largest body that makes repetitive close passes to the earth and moon! You may never look at the Perseids the same after reading this.
