The Perseid Meteor shower is an annual event that begins in July, but peaks in mid-August. There are six types of annual meteor showers which all have different reasons in terms of why they happen.
As far as the Perseid is concerned, it is the result of the debris from the 109P/Swift-Tuttle comet. The Perseid meteor shower is the most visible and well-known of its kind.
Although the peak is during the night between August 12th and August 13th; as long as there is a clear sky and even better less light outside, people are still able to view them other nights in the months of July and August. NASA reports that as of Tuesday August 9th, approximately twelve meteors were seen per hour.
Unfortunately, there will be a full moon the night that the meteor shower peaks which will make it harder to notice the smaller meteors; however, there will still be a nice show to see. Also, it is expected that there will be more meteor showers before dawn on Saturday.
The best part about this show is that it is free and viewable from home. Some people also decide to go for a drive where there are fewer lights; making smaller ones easier to see.
