Star-gazers get ready! An annual celestial event is expected to peak Thursday and Friday. 

It is called the Perseid Meteor Shower and astronomers are expecting to see a near double in the number of meteors from typical years.

David Mues, Planetarium Coordinator at the Powerhouse Science Center in Sacramento says that Earth is entering a special part of its orbit.

"We are actually crossing a trail of comet dust. Comet Swift-Tuttle orbits the sun, and as it does so, the ices that make up the comet vaporize," Mues said.

He says when those ices vaporize, dust that was trapped in that ice creates a dust trail, or meteor shower.

Officials at NASA say that the typical Perseid Shower has about 80 to 100 meteors per hour, but this year they are expecting 160 to 200 meteors per hour.

Mues says how well you can see them all depends on how much light is around you and the time of night.

"My theme is always later is better and latest is best. After midnight, ideal, after the wee hours, is better," Mues said.

The shower is expected to peak Thursday and Friday, but if you do not get the chance to see it in the next couple days, do not worry. NASA will be live streaming the spectacular here.
