here do the Perseids take their name from?

Most meteor showers are named after the constellations where their radiant is located. The radiant is a point in the sky from which all meteors belonging to a single shower appear to originate. The Perseids’ radiant is located in the constellation Perseus, hence their name.

Some meteor showers can take their name from bright stars (like the Eta Aquarids) or former constellations (like the Quadrantids).

hat causes the Perseid meteor shower?

The parent body of the Perseids is comet Swift-Tuttle. As this comet travels through space, it leaves a trail of debris along its orbit. When our planet passes through this dust trail, tiny comet particles enter the Earth’s atmosphere and burn up, producing bright streaks of light in our skies — the Perseid meteors.

Comet Swift-Tuttle takes 133 years to complete one orbit around the Sun. The last time it was observed from the Earth was in 1992, and the next time it will visit us only in 2126. Despite being such a rare guest in the inner Solar System, the comet leaves behind enough cosmic dust for us to enjoy the Perseids every year.

hen should I watch the Perseids in 2021?

According to the International Meteor Organization (IMO), the Perseid meteor shower will be active from July 17 to August 24. This means you can try your luck and go catch some “shooting stars” tonight. However, it’s better to wait until the shower’s peak when the meteor rate reaches its maximum. The IMO states that this year, the Perseids will peak on the night of August 11–12. During the peak, you’ll be able to see up to 60 meteors per hour if the sky is dark enough. The best time for watching the Perseids is between midnight and dawn.

Fortunately, this year, the Moon won’t spoil your meteor observations — on the Perseids’ peak night, it will be only 13% full. With only a thin crescent lighting up the sky, you’ll surely be able to spot “shooting stars”.

he Perseids observing tips

Here are a few tips that will help you fully enjoy the Perseid meteor shower and catch the most meteors.

- Check the weather forecast in advance. Clouds may block the view and prevent you from seeing any “shooting stars”.

- Get away from city lights. Light pollution is your worst enemy, so try to find an unobstructed horizon in the countryside.

- Wait until the radiant reaches its highest point in the sky. The higher the shower’s radiant, the more meteors you’re likely to see. To locate the radiant, you can use the Star Walk 2 stargazing app.

- Use your naked eyes to observe meteors. Binoculars and telescopes will narrow your field of view and reduce your chances of seeing meteors.

- Look some distance away from the radiant. Though all the meteors seem to fly out of the radiant, there’s no need to look directly at it. You’ll have a better chance of spotting “shooting stars” if you look from 45 to 90 degrees away from the radiant.

- Pack some warm clothes and a thermos with a hot drink. You may get cold while waiting for meteors to appear.

- Lay back on a blanket or a reclining chair — it’s much more comfortable than standing.

- Give your eyes about 30 minutes to adjust to the dark in order to see more meteors.

- Avoid looking at any white light — it will ruin your night vision, and you’ll have to wait until your eyes re-adjust to the dark. Our eyes are less sensitive to red light, so if you need to use a flashlight, place a red filter on it. If you’re using Star Walk 2, don’t forget to turn on the Night Mode — it will make the screen red.
