The Lyrid meteor hit in late April. While the swim isn’t as brilliant as the others over the year, the Lyrids are known to have high levels of performance. Average rainfall shows between five and 20 meteors per hour at the peak, but some of the best shows are 100 or more meteors per hour.
In 2022, it will rain on Earth around April 14-30, and the peak is expected to be on the night of April 22.
Chinese astronomers recorded rain until 687 BC, according to NASA. The cause of the meteors was Comet Thatcher, which was seen by astronomer AE Thatcher when it came very close to the solar system in 1861. The comet is expected to return in 2276.

Lyrid meteor rain can be seen
The Lyrids have been written in many cultures over the past 2,700 years. Chinese astronomers saw important observations in 687 BC and 15 BC Also, in 1136, a report from Korea reported swimming with the words “many stars flew from the north. east, ”according to Space.com historian Joe Rao.
In 1803, residents of Richmond, Virginia, went outside at night after a fire broke out. There have been reports since then that meteors are like rocks in the sky.
“Shooting star. This lightning [sic] Just this past Wednesday morning, something amazing was seen in Richmond and its environs, in such a way as to astonish the public, and to the astonishment of all who saw it. From 1 o’clock to 3 o’clock in the morning, it was as if those meteorites were falling from all over the sky, in numbers like the rain of celestial rockets, “he said. the journalist at the time, in an article republished in Space Weather.

NASA reported that it had seen heavy rain in 1922 in Greece, 1945 in Japan, and 1982 in the United States.

Where are the Lyrids?
The Lyrids seem to be coming from Vega, the shining beginning of the Lyra constellation, which is called meteor water. The “radiant” point is easy to see in the summer sky because Vega is one of the brightest stars, seen in places with light pollution. However, meteors are best seen under a dark sky.
Location of Lyra:
– Accurate ascent: 19 hours
– Reduction: 40 degrees
– Latitudes: Between 90 and -40 degrees
NASA expects astronauts to go outside after Lyra’s ascent (after 9 p.m., and after the moon’s setting, to watch the show, which is flying until dawn.Allow 30 minutes to correct the eyes, and look at the distance from the glare, where the meteors can be seen longer.A close look at Lyra will reveal short meteors due to a phenomenon called foreshortening.
While the Lyrids aren’t the best out there, NASA says the meteors “are known for their light earth vehicles, which can be seen for a few seconds.” A typical meteor from that rain would move about 30 miles (49 kilometers) per second.
While the swim was coming out of Lyra, the meteors were fragments left over from Comet Thatcher.

Comets are removed when snow and other debris are removed from the base. This leaves a trail of rubbish in the air. In the case of Thatcher’s path of trash, Earth traveled within a year and released a meteor shower called the Lyrid meteor shower.
It is difficult for astronomers to predict the years that heavy rainfall will occur, the North American Meteor Network found in a report from 1999. (opens on new page).
“Orbit determination relies heavily on imaging and radar results, which can’t be obtained every year – hence the gaps in the data and our perception of rainfall,” he wrote. the system. “The lessons of the years have been seen with high Lyrid activity, however, meteors’ damage has been more severe than the size of a normal meteor.”
