Google Doodle celebrates spectacular meteor shower

The search engine Google has created an interactive doodle to celebrate the Perseid meteor shower that occurs every August.

The spectacular annual celestial phenomenon began Saturday and is expected to finish Wednesday while reaching its peak Tuesday.

It is caused when the massive Swift-Tuttle comet loses parts of its celestial body as it enters into the inner solar system.

With clear skies, it is common to see more than 100 meteors an hour.

The Perseids get its name as the meteors look like they originate from the constellation Perseus.

Comet Swift-Tuttle last passed earth in 1992 and travels in a 133 year orbit around the sun.
