2023 Perseid meteor shower observed in Chinese grasslands

The Perseid meteor shower is one of the best opportunities to see hundreds of shooting stars, and this year it will peak around August 12 and 13. The shower is expected to last from mid-July until the end of August, but the most meteors will be visible during the dawn hours near the peak.
What is the Perseid meteor shower?
Meteor showers occur when the Earth passes dust and debris drifting behind a comet. These tiny particles of debris slam into the atmosphere at incredible speeds, and friction with the atmospheric particles causes the dust to heat up and burn up, leaving only a flash of light in the air. This moving flash is called a shooting star or meteor.
The Perseid meteor shower is caused by the comet Swift-Tuttle, which orbits the Sun every 133 years. Once a year, Earth passes through its debris trail, lighting up the sky with meteors.
When should you view the Perseid meteors?
The best days to view the Perseid meteor shower are within a few days of its peak – outside of that period you may see some, but they won’t be as impressive.
Meteors can be seen at any time of the night, but a bright moon can make them harder to spot. This year, a half moon will be visible at the peak, so the best time to look for meteors is midnight after the moon has set. This is true for observers around the world, but the best views of the Perseid meteor shower will be in the Northern Hemisphere due to the orientation of the Earth relative to the comet’s debris trail.
How many meteors can we see this year?
Typically, the Perseids emit between 50 and 100 meteors per hour during the peak of the meteor shower. They can also produce fireballs, which are bright meteors that are created when a large chunk of a comet impacts Earth’s atmosphere. The number of meteors visible from a particular location depends on the level of light pollution, so getting away from city lights is essential if you want to see as many meteors as possible.
How do you observe the Perseid meteor shower?
The best way to observe the meteor shower is to be in as dark a place as possible with as much sky as possible visible. The Perseid meteors appear to streak towards the constellation Perseus, but they will appear all over the sky. It may take up to 30 minutes for your eyes to adjust to the darkness. Don’t be discouraged if you can’t see anything at first. To allow your eyes to adjust, look at the sky as much as possible without looking at street lights, cell phones or even the moon. When you see a tiny point of light streaking across the sky for a few seconds or less, that’s the Perseid meteor shower.
