The meteors seem to originate from a point in the constellation of Orion, which is where their name comes from.
The visible trails are clumps of debris left behind by the famous Halley's Comet as it follows its orbit around the sun.
The debris enters our planet’s atmosphere at speeds of around 41 miles per second - now that's fast.
It vaporises, which means something turns from a solid or liquid into a gas, from friction with the air causing the streaks of light we call meteors.
These can last in the sky from several seconds to minutes.
Halley's Comet is only seen from Earth about once every 75 years - the next time is thought to be around the year 2061, so don't worry, you haven't missed it recently!
The Orionids is one of two meteor showers created by debris from Halley's Comet.
The other is the Eta Aquariids meteor shower, which appears earlier on in the year, around May.
