Thanks to CTOnews.com netizens for the delivery of clues on the way! CTOnews.com, August 11 (Xinhua)-- the Perseid meteor shower will reach its maximum in the early hours of the 13th, with more than 100 ZHR (zenith flow per hour). Astronomical forecasts show that this year's Perseid meteor shower is highly expected to occur between 15:00 and 22:00 on August 13.

CTOnews.com learned from the Wiki Encyclopedia that the flow of debris extending along the orbit of Comet Swift-Tuttle is called the Perseus Cloud and consists of particles ejected by the comet during its 133-year orbit. Meteor showers begin to appear in mid-July each year, and the peak of activity occurs between August 9 and 14, depending on the specific location of the meteor flow.

Meteor showers usually produce long and bright tracks, sometimes fireballs, as they pass through the earth's atmosphere. Most Perseid meteors burn in the atmosphere at an altitude of more than 80 kilometers (50 miles).
