The Perseid shower peaks tonight when up to 100 meteors an hour can be spotted.
The Perseid shower is the most spectacular of the year as more meteors are visible than that of any other shower and often big ‘fireballs’ can be spotted.
It comes around every summer when Earth passes through the trail of dust and debris left in the orbit of the very large Comet Swift-Tuttle, which passes near Earth every 133 years on its journey around the sun.
The meteors blaze through the sky as pieces of debris burn up in the atmosphere, travelling at 37 miles per second.
Most Perseid meteors are made of pieces of dust about the size of a grain of sand, and almost all of them burn up completely on their way through the atmosphere.
Meteor showers happen when bits of ice and dust, which can be as small as a grain of sand or as big as a pea collide with the earths atmosphere at 134,000mph.
Heading out to areas away from light pollution, such as the countryside, will give you the greatest chance of seeing meteors.
The chances of spotting meteors will also be weather dependent, as clear skies give the best viewing opportunities.
