Can you see the 20 12 Perseid meteor shower in Puning, Jieyang, Guangdong?
On the night of August 12- 13, the Perseid meteor shower is expected to peak at 100 meteors per hour (ideally), which will actually be discounted to varying degrees.
cause
The cause of Perseid meteor shower is related to comets, which are spheres made of ice and sand. When a comet approaches the sun, it will sublimate the surface substances due to the heat of the sun, and these sublimated substances will become meteoroids in the future. During the comet's orbit around the sun, some meteors will leave the comet and stay in its orbit, while meteoroids will continue to spread away from each other due to solar pressure and planetary forces, and their range will gradually increase.
When the orbit of the earth intersects with the orbit of the comet, the meteor will break into the earth's atmosphere and burn under the action of the earth's gravity. The bright flame produced when burning is the meteor shower that people see. If there are many meteoroids scattered in the orbit of the comet, meteor showers caused by meteoroids produced by the comet can still be seen within a few years after the comet returns.
