What causes a meteor shower?

What are meteor showers? These meteors are caused by cosmic debris called meteoroids which enter the earth’s atmosphere at extremely high speeds on parallel trajectories. Nasa says on its website: “Fast meteors can leave glowing “trains” (incandescent bits of debris in the wake of the meteor) which last for several seconds to minutes.

What is the name of the meteor shower that spawned the Perseid meteor shower?

The Perseid meteor shower is spawned by the comet Swift-Tuttle, formally designated 109P/Swift–Tuttle. Every year, our planet crosses the comet’s orbital path and passes through a trail of debris, with bits and pieces of the comet slamming into the Earth’s upper atmosphere. Perseid meteor shower.

Why is the meteor shower associated with Perseus?

The meteor shower is associated with Perseus because the radiant, or the point from which the Perseids appear to come in the sky, is located in the direction of Perseus constellation. The name Perseids is pronounced /?p?rsi??dz/.

How fast do perseids travel?

These meteoroids travel at more than 100,000 miles per hour and leave streaks of light as they ignite and vaporize in the Earth’s upper atmosphere.

What is the trail of debris that appears as falling stars to viewers called?

The trail of debris that appears as falling stars to viewers stretches along the orbit of Swift-Tuttle and is called the Perseid cloud. The comet has a 133-year orbit and ejects particles as it travels. These particles form the Perseid cloud and have been part of it for about a thousand years.

What was the magnitude of the Perseids in 2013?

In 2013, the average peak apparent magnitude for the Perseids was -2.7, significantly brighter than the peak magnitude for the Geminids (-2).

What are the Perseids known for?

The Perseids are notable for their fireballs, larger bursts of light and colour that originate from larger pieces of cometary debris and can be visible longer than regular meteors. They are also usually brighter, with magnitudes reaching more than -3.

When is the Perseid meteor shower?

Perseid Meteor Shower. The Perseid meteor shower is an annual meteor shower that occurs from July 23 to August 20. The meteor shower is associated with the comet Swift-Tuttle. It peaks around August 12-13 every year. The Perseids are also sometimes called the “tears of St. Lawrence” because they peak near the date of the saint’s martyrdom, …

Why are fireballs brighter than meteors?

Fireballs are larger explosions of light and color that can persist longer than an average meteor streak. This is due to the fact that fireballs originate from larger particles of cometary material. Fireballs are also brighter, with apparent magnitudes greater than -3.

What are the most abundant meteor showers?

The Perseids are one of the most plentiful showers (50-100 meteors seen per hour) and occur with warm summer nighttime weather, allowing sky watchers to easily view them. Perseids are also known for their fireballs. Fireballs are larger explosions of light and color that can persist longer than an average meteor streak.

What constellation is the meteor shower in?

Their radiant—the point in the sky from which the Perseids appear to come from—is the constellation Perseus. This is also where we get the name for the shower: Perseids. However, the constellation for which a meteor shower is named only serves to aid viewers in determining which shower they are viewing on a given night.

How long does it take for a comet to orbit the Sun?

Swift-Tuttle takes 133 years to orbit the sun once. It was Giovanni Schiaparelli who realized in 1865 that this comet was the source of the Perseids. Comet Swift-Tuttle last visited the inner solar system in 1992. Comet Swift-Tuttle was discovered in 1862 by Lewis Swift and Horace Tuttle.

When do the Perseids peak?

The Perseids, which peak during mid-August, are considered the best meteor shower of the year. With very fast and bright meteors, Perseids frequently leave long "wakes" of light and color behind them as they streak through Earth’s atmosphere.

When was the comet Swift Tuttle discovered?

Comet Swift-Tuttle was discovered in 1862 by Lewis Swift and Horace Tuttle. Swift-Tuttle is a large comet: its nucleus is 16 miles (26 kilometers) across. (This is almost twice the size of the object hypothesized to have led to the demise of the dinosaurs.)

What happens when comets come around the Sun?

When comets come around the sun, they leave a dusty trail behind them. Every year Earth passes through these debris trails, which allows the bits to collide with our atmosphere and disintegrate to create fiery and colorful streaks in the sky.

What Time Does the Meteor Shower Peak?

The table is updated daily and shows the position of the Perseids radiant in the sky for the upcoming night. Use the date drop down above the Interactive Meteor Shower Sky Map to change dates.

How to see Perseids?

How to See the Perseids 1 Find a secluded viewing spot, away from the city lights. Once at the venue, your eyes may take 15 to 20 minutes to get used to the dark. 2 Dress for the weather, and make sure you are comfortable, especially if you plan to stay out long. Bring a blanket or a comfortable chair with you—meteor watching can be a waiting game. 3 Once you have found your viewing spot, lie down on the ground and look up in the direction of the radiant. Use our Interactive Meteor Shower Sky Map or the table above to find the current direction of the radiant in the sky.

Why are Perseids named after Perseus?

This is because the direction, or radiant, from which the shower seems to come in the sky lies in the same direction as Perseus.

What is azimuth based on?

Azimuth is the direction, based on true north; a compass might show a slightly different value.

When will the meteor showers peak in 2021?

Northern Hemisphere (Best) List of meteor showers. In 2021, the Perseids will peak on the night between Aug 12–13.

What is the source of the Perseid meteor shower?

What’s the source of the Perseid meteor shower? Every year, from around July 17 to August 24, our planet Earth crosses the orbital path of Comet Swift-Tuttle, the parent of the Perseid meteor shower. Debris from this comet litters the comet’s orbit, but we don’t really get into the thick of the comet rubble until after the first week of August. The bits and pieces from Comet Swift-Tuttle slam into the Earth’s upper atmosphere at some 130,000 miles (210,000 km) per hour, lighting up the nighttime with fast-moving Perseid meteors.

How many meteors can you see in a Perseid shower?

4. You want a dark sky for watching meteors. In a dark sky, you may see up to 60 meteors per hour at the shower’s peak.

What is the name of the meteor that burns up 60 miles above Earth’s surface?

However, this is a chance alignment of the meteor shower radiant with the constellation Perseus. The stars in Perseus are light-years distant while these meteors burn up about 60 miles (100 km) above the Earth’s surface. If any meteor survives its fiery plunge to hit the ground intact, the remaining portion is called a meteorite. Few – if any – meteors in meteor showers become meteorites, however, because of the flimsy nature of comet debris. Most meteorites are the remains of asteroids.

Why is the meteor shower named after Perseus?

Hence, the meteor shower is named in honor of the constellation Perseus the Hero. However, this is a chance alignment of the meteor shower radiant with the constellation Perseus. The stars in Perseus are light-years distant while these meteors burn up about 60 miles (100 km) above the Earth’s surface.

How to watch the Perseids in 2021?

7. If you must watch in moonlight, place yourself in the moon’s shadow. In 2021, the moon will be in a waxing crescent phase, setting in the west in early evening, as the Perseids peak. So the moon won’t be a factor for the Perseids’ peak this year. But maybe you want to start watching for Perseids in late July, when there’s a moon in the sky between midnight and dawn? If so, place some large structure or natural object – a barn, a cabin, a mountain – between you and the moon. You’ll see more meteors that way than if you’re standing out under the blazing moonlight itself.

How to watch meteors?

Here’s the first thing – the main thing – you need to know to become as proficient as the experts at watching meteors. That is, to watch meteors, you need a dark sky. It’s possible to catch a meteor or two or even more from the suburbs. But, to experience a true meteor shower – where you might see several meteors each minute – avoid city lights. EarthSky’s Best Places to Stargaze page shows dark locations worldwide. Once you choose your dark area, you can watch from many sorts of areas: a rural backyard or deck, the hood of your car, the side of a road. State parks and national parks are good bets, but be sure they have a wide open viewing area, for example, a field. You don’t want to find yourself stuck in a forest on meteor night. An EarthSky friend, veteran meteor-watcher and astrophotographer Sergio Garcia Rill, also offers this specific advice:

How many meteors per hour are in the Taurids?

Thus the Taurids are extremely long-lasting (September 25 to November 25) but usually don’t offer more than about five meteors per hour. That is true even on their peak nights.

When can you see meteors in 2021?

In 2021, watch the Draconid meteors at nightfall and early evening on October 8. You might catch some on the nights before and after, as well. Fortunately, the thin waxing crescent moon sets before nightfall. It won’t hinder this year’s Draconid shower. The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere. The Draconid shower is a real oddity, in that the radiant point stands highest in the sky as darkness falls. That means that, unlike many meteor showers, more Draconids are likely to fly in the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour.

When is the Delta Aquariid meteor shower?

You’ll still be seeing Delta Aquariids when the Perseids peak in August. Like the Eta Aquariids in May, the Delta Aquariid meteor shower in July favors the Southern Hemisphere and tropical latitudes in the Northern Hemisphere. It’s well viewed from latitudes like the southern U.S.

When will the Delta Aquariids be in 2021?

Late July 2021 , before dawn, Delta Aquariids. At this shower’s peak on or near July 27-30, 2021, the rather faint Delta Aquariid meteors will fall most abundantly in the predawn hours, though in the glaring light of a waning gibbous moon. Never fear. You’ll still be seeing Delta Aquariids when the Perseids peak in August.

When will the ETA Aquariid meteors come down?

May 5, 2021, before dawn, Eta Aquariids. In 2021, the most Eta Aquariid meteors will likely rain down in the hour or two before dawn on May 5, though under the light of a rather wide waning crescent moon.

Why are meteors greater at northerly latitudes?

Because the radiant is fairly far to the north on the sky’s dome, meteor numbers tend to be greater at northerly latitudes in the Northern Hemisphere.

Observing prospects

At its peak, the shower is expected to produce a nominal rate of around 5 meteors per hour ( ZHR ). However, this zenithal hourly rate is calculated assuming a perfectly dark sky and that the radiant of the shower is situated directly overhead. In practice, any real observing sight will fall short of these ideal conditions.

The origin of the shower

Meteor showers arise when the Earth passes through streams of debris left behind in the wake of comets and asteroids. Over time, the pieces of grit-like debris in these streams distribute themselves along the length of the parent object’s orbit around the solar system.


The position of the radiant of this shower, and its predicted hourly rate, were taken from International Meteor Organisation’s List of Meteor Showers .
