Unknown object falling over Jiaxing, Zhejiang. What could it be? Is it a meteorite or something?
Because space is a vacuum, there is no air, so there is no heat conduction in space, only thermal radiation, so there are complex material forms in space, from black holes and stars to various ions and electrons. Frequent visitors to the earth are a special kind of natural solid debris called meteorites. They are meteors or dust fragments floating in the unexpected space of the earth's atmosphere, entering the earth's atmosphere in motion, passing through the atmosphere and falling to the earth's surface. Silicate, the main component of meteorites, also contains iron and nickel, and some meteorites also contain some complex compounds of organic matter and carbon, which are the most basic substances for synthesizing life, so there is a saying that some life on earth comes from outer space and some forms on earth.
When meteorites or fragments of meteorites in space enter the earth's atmosphere at the speed of the second universe, because the thickness of the earth's atmosphere is very large, meteorites or fragments of meteorites rub against the earth's atmosphere during the movement. When air rubs against meteorites, it will produce high temperature, which can reach thousands of degrees Celsius. Under the action of this high temperature, the oxygen on the surface of the meteorite and in the air will start to oxidize and burn, and the compounds produced in the burning process will gradually be separated from the meteorite or meteorite fragments. Finally, meteorites. The greater the mass of meteorites or meteorite fragments, the greater the mass that eventually falls on the earth. On the contrary, the smaller the mass, the smaller the final landing mass. The unidentified object in Jiaxing, Zhejiang Province is a relatively small meteorite in space. After the atmosphere is stripped off, it eventually becomes very small.
