VIDEO: Perseid Meteor Shower Visible Saturday

The night sky will light up with an annual meteor shower with best views in the northern hemisphere, astronomers said.

The Perseid Meteor Shower 2012 will be visible late Saturday night and early Sunday morning. Up to 100 meteors an hour may be seen, according to NASA.

The Perseid shower is named after Perseus, the constellation from which the meteors appear to originate.

The shower is the result of the Earth’s orbit through a cloud of debris left by the Swift-Tuttle comet, which orbits the sun once every 133 years.

And since the entire Earth is sweeping through the icy, dusty debris, the meteors can be seen all over the sky, though all meteors that are a part of the shower can be traced back to the constellation.

The shower is expected to be visilbe between 11 p.m. and 3 a.m. NASA is running a live chat during the shower.
