The annual Leonid meteor shower will reach its peak tonight when an average of 20 shooting stars visible streaking across the night sky every hour.
Known for their brightness and colour, the Leonids feature some of the fastest moving rocks of any of the annual showers – travelling at 44 miles per second.
Stargazers should see about 20 meteors per hour if the sky is clear, made easier to spot by the dark waxing crescent Moon that is only about two per cent full.
You can view the shooting stars by looking to the East towards the direction of the constellation of Leo – but find an area with clear skies with low light pollution.
Most of the UK is expected to be covered in clouds over the next 24 hours, so finding a clear sky may prove difficult, according to the UK Met Office

To get the most out of the annual show, head outside just after midnight and use a wide-angle lens to get as much of the sky as possible if you want to get pictures.
NASA says the best way to view the shower is to find an area well away from street lights, dress up warm and lie flat with your feet towards the east.

In the US there should be mostly clear skies during the peak time except for some storms along the West Coast of the country.
The shooting stars travel at around 45 miles per second (72km/s) and around half of them leave visible trains that sometimes linger for seconds after.
The Leonid shower occurs when meteoroids, small rocks, fall towards the Earth after breaking off from the Comet Tempel-Tuttle.
These burn up and vaporise before they hit the Earth’s surface – causing a streak of hot air which we see as a shooting star.
Displays are better when the Tempel-Tuttle comet, which takes 33 years to orbit the sun, is closer to the Earth, an occurrence which is next due in about 15 years’ time.
Since meteoroids that create a meteor shower all move on a parallel path, and at the same speed, they seem to originate from a single point in the sky to observers on Earth, known as the radiant.

The Leonid meteor shower gets its name from its radiant, the point at which the meteors appear to emerge from in the constellation Leo.
Every 33 years, the Leonid meteor shower arrives as a storm of meteors, with more than 1,000 shooting stars an hour.
In 2034, researchers predict that observers will have a chance to witness 2,000 meteors per hour, in a ‘Leonid storm.’
The next major meteor shower in the sky will be the Geminids in the middle of December. This is the strongest meteor shower of the year with 120 meteors per second.
Explained: The difference between an asteroid, meteorite and other space rocks
An asteroid is a large chunk of rock left over from collisions or the early solar system. Most are located between Mars and Jupiter in the Main Belt.
A comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.
A meteor is what astronomers call a flash of light in the atmosphere when debris burns up.
This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.
If any of this meteoroid makes it to Earth, it is called a meteorite.
Meteors, meteoroids and meteorites normally originate from asteroids and comets.
For example, if Earth passes through the tail of a comet, much of the debris burns up in the atmosphere, forming a meteor shower.
