The Orionids are particularly fast and can leave trails in the sky that last a few seconds after the meteor itself has gone.

The display occurs at around the same time each year when the Earth passes through a trail of dust and debris left behind by Halley's Comet.

The showers peak overnight from 21 to 22 October.

The Orionids are particularly fast, entering the atmosphere at around 41 miles per second.

As tiny particles from Halley's comet enter the Earth's atmosphere they heat up and produce streaks of light across the night sky that we see as meteors.

Halley's Comet is one of the most famous comets in our Solar System and has been observed from Earth for centuries. It takes around 76 years to complete one orbit of the Sun and was last seen from Earth in 1986.

Halley's Comet is not expected to be visible from Earth again until 2061, but its debris will continue to produce meteor showers each year.

In fact, the Earth encounters material left behind by it twice a year, resulting in the Eta Aquariid meteor shower in May and the Orionids in October.

The meteors appear to radiate from the constellation of Orion, which is where the shower gets its name, but they can appear anywhere across the night sky.

Under ideal conditions, around 10 to 20 meteors can be seen each hour at the shower's peak.

The constellation of Orion is one of the most recognisable in the night sky identifiable by the large hour glass shape formed by some of its stars For the best chance of seeing them, find a dark location away from street lights and with as wide a view of the sky as possible.

You won't need binoculars or a telescope; the shower is best viewed with the naked eye. Later in October, the Moon could affect how many meteors are visible at the peak of the Orionids, as as it builds to its full phase on 26 October.

This means its light could make some of the fainter meteors more difficult to see.
（暂无翻译）
Brighter meteors, however, should still be visible, particularly from darker locations away from artificial light.

You will have noticed over the weekend that temperatures across the UK have dropped and it feels much more like autumn now.
（暂无翻译）
The cooler feel will continue through this week, so if you do plan to spend time outside gazing at the sky, make sure you are wrapped up.

As the meteor shower peaks on Wednesday night, it currently looks as though rain will move away early in the night, leaving most areas with a clear view of the sky at times.
（暂无翻译）
If you are not planning on viewing the shower until later this week, there is a chance that we could see much wetter and windier conditions sweep across parts of the country.
