How to watch the Orionids meteor shower in the UK

Of all the meteor showers that occur in the year, the Orionids is one of the best known and most spectacular.

On good years, up to 25 shooting stars can be spotted every hour as they blaze across the night sky.

You don’t need any special equipment to enjoy the meteor shower, just a good viewing spot, a little patience and – hopefully – good weather conditions.

Many people consider the Orionids the best meteor shower because the tiny chunks of rock that burn up in our atmosphere are actually fragments from Halley’s comet – one of the most famous comets there is.

Halley’s comet is visible from Earth every 76 years. It was last seen in our skies in 1986 and won’t come round for another pass until 2061. It’s been viewed and recorded by astronomers since at least 240BC.

Even if you haven’t seen Halley’s comet for yourself, you’ll get to see parts of it if you stay up and watch the Orionids this week.

‘The Orionids, which peak during mid-October each year, are considered to be one of the most beautiful showers of the year,’ explained Nasa.

‘Orionid meteors are known for their brightness and for their speed. These meteors are fast—they travel at about 148,000 mph (66 km/s) into the Earth’s atmosphere.

‘Fast meteors can leave glowing “trains” (incandescent bits of debris in the wake of the meteor) which last for several seconds to minutes. Fast meteors can also sometimes become fireballs.’

As both the Earth and Halley’s comet have elliptical orbits around the sun, the two intersect twice every year, causing not only the Orionids, but also the Eta Aquariid meteor shower in May.

When will the Orionids meteor shower peak above the UK?

This year, the Orionids will reach its peak this evening, the night of Thursday, October 21.

Your best chance to see it will be between midnight and dawn.

This year, weather conditions aren’t as favourable so there may be less visible meteors than in previous years.

The Royal Observatory Greenwich has advised you may see up to 15 meteors per hour this year.

How long will the Orionids be visible for?

The good news is that the Orionids isn’t just visible over its peak, but for quite a long time afterwards as well.

It should remain visible in both northern and southern hemispheres until around November 7.

So, if you get a clear night between now and then – it could well be worth wrapping up warm and heading out for another chance to spot the shooting stars.

After sunset the meteors could start to become visible, but your best chance to see them will be after 10pm. The official ‘peak time’ for spotting meteors is around midnight.

You will need to look upwards and eastwards into the night sky – near the constellation of Orion – for the best chance of spotting the meteors.

Anna Ross, an astronomer at the Royal Observatory Greenwich, explained: ‘Meteors will be visible all over the sky but they will appear to originate from close to the star Betelgeuse in the constellation of Orion, which will be in the east of the sky during that peak time.

As ever, the best way to see them is to get as far away from light pollution as possible and just look upwards.

You’ll need to spend some time, around 15 minutes or so, letting your eyes adjust to the darkness.

What causes the Orionids meteor shower?

The Orionids are caused by the Earth’s orbit bringing it into contact with debris from Halley’s comet.

Halley takes around 76 years to make a complete revolution around the Sun. It will next be visible from Earth in 2061.

Nasa explained: ‘Each time that Halley returns to the inner solar system its nucleus sheds ice and rocky dust into space. The dust grains eventually become the Orionids in October and the Eta Aquarids in May if they collide with Earth’s atmosphere.’

The cometary debris enters our planet’s atmosphere at speeds of around 41 miles per second, vaporising from friction with the air causing the streaks of light we call meteors.
