Perseids is a meteor shower that allows people to see some meteors easily. Colorado residents have a great opportunity this year to catch the view of falling meteors.

Well, this show is the result of leftover bits and pieces of a comet falling on earth. A dusty-rocky trail is left behind after comets pass by the sun. Then comes in play the earth which passes through these trails. Those little rocks and bits of dust burn up in earth's atmosphere, setting a show in the sky. The streaks of light, fire seen in our sky are actually falling debris.

The upcoming dusty-trail event belongs to a comet named 109P/Swift-Tuttle. Lewis Swift and Horace Tuttle discovered this comet in 1862 and it was later learnt that it takes 133 years to orbit the sun.

The size of the comet is believed to be double the size of the asteroid that pushed dinosaurs to extinction. There is no need to worry from this comet as it is not going to collide with earth, but its dusty/rocky trail left behind certainly will.

The pre-dawn hours are the best for viewing, says NASA, adding the late-evening could also allow to see them, but one must get away from city lights to get a good view.

Although this shower is active from July 13th, the peak will be reached on August 12 and 13, when up to 100 meteors per hours will be seen. The Geminids is the other must-see meteor shower this year in December.
