The Eta Aquarids, often known as the Eta Aquariids, is the primary of a pair of meteor showers that originate from Halley’s Comet, probably the most famend cosmic physique of all of them. This 12 months, the Eta Aquarids bathe will attain its peak on Might 6.
The unhealthy information for these within the UK is that the bathe is extra spectacular within the Southern Hemisphere, the place observers can witness round 20 to 30 meteors per hour throughout its peak. In the meantime, stargazers within the Northern Hemisphere can solely anticipate to see half as many.
The bathe produces taking pictures stars when the Earth passes alongside Halley’s particles stream, which, in flip, creates tiny particles that burn within the higher environment.
However don’t fret if you happen to miss out on seeing the Eta Aquarids, as there are many different alternatives to see the sky stuffed with streaks of sunshine.
Right here, we’ve compiled a whole information on when, the place and how one can see all of the meteor showers of 2022.
What precisely is a meteor bathe?
A meteor bathe happens when Earth passes by means of the particles stream occupying the orbit of a comet or, in less complicated phrases, when numerous meteors flash throughout the sky from roughly the identical level.
Meteors are generally known as taking pictures stars, though they really don’t have anything to do with stars.
Perspective makes meteor showers seem to emanate from a single level within the sky generally known as the bathe radiant. The everyday meteor outcomes from a particle – the dimensions of a grain of sand – vaporising in Earth’s environment when it enters at 134,000mph.
Something bigger than a grape will produce a fireball, which is usually accompanied by a persistent afterglow generally known as a meteor prepare. This can be a column of ionised gasoline slowly fading from view because it loses power.
Meteor, meteoroid or meteorite?
A meteor is a meteoroid – or a particle damaged off an asteroid or comet orbiting the Solar – that burns up because it enters the Earth’s environment, making a “taking pictures star”.
Meteoroids that attain the Earth’s floor with out disintegrating are known as meteorites.
Meteors are largely items of comet mud and ice no bigger than a grain of rice. Meteorites are principally rocks damaged off asteroids within the asteroid belt between Mars and Jupiter and weigh as a lot as 60 tonnes.
They are often “stony”, made up of minerals wealthy in silicon and oxygen, “iron”, consisting primarily of iron and nickel, or “stony-iron”, a mix of the 2.
Scientists take into consideration 1,000 tons to greater than 10,000 tons of fabric from meteors falls on Earth every day, but it surely’s largely dust-like grains, in keeping with NASA, they usually pose no menace to Earth.
There are solely two recorded incidents of an damage attributable to a meteorite. One among these situations noticed a lady bruised by a meteorite, weighing eight kilos, after it fell by means of her roof in 1954.
Meteor showers in 2022
Perseid meteor bathe
The Perseid meteor bathe will hit its peak between August 12 and 13 in 2022, permitting stargazers to witness round 160 and 200 meteors coming into Earth’s environment each single hour. The bathe is especially distinguished within the Northern Hemisphere, within the pre-dawn hours, and is without doubt one of the hottest showers, as if it isn’t the strongest, its spectators can get pleasure from it throughout summer season.
Throughout its peak, the Perseids sparkle in the summertime sky, when the Earth collides with particles of particles left behind by the Swift-Tuttle Comet.
In 2021, the Moon was solely 13 per cent full and set because the meteors started to appear – permitting viewers to see round 50 to 75 meteors per hour on its optimum evening.
The bathe discovered its identify from the Greek phrase, Perseidai, which means the sons of Perseus in Greek mythology, which refers back to the level wherein they seem to hail.
