Perseid meteor shower: How to watch the cosmic spectacle [video]

The annual Perseid meteor shower reaches peak on Tuesday, August 11, when it`s supposed to offer the best meteor show of the year, according to NASA. Sky watchers will be able to see dozens of bright meteors per hour on the late summer sky.

Shortly after twilight, long-tailed meteors will start crossing the lower parts of the sky. The cosmic spectacle will get more animated as the Earth rotates.

To watch the Perseids, find a spot with a clear view of the sky, far away from artificial lights. Just lay down and watch the sky, the cosmic spectacle will develop by itself.

The optimal time to observe the Perseids is between 2 AM, your local time, and dawn. During this period there will be one meteor every two minutes.

Every year, Earth`s orbit intersects with a cloud of debris left by Comet Swift-Tuttle. The rocky debris have the size of sand grains / beans, and cross Earth`s atmosphere at 60 km per second.

The Perseid meteor shower started on July 14 and will last until August 24.
