How to identify meteorites
1, molten shell
Meteorites enter the atmosphere at a very fast speed, and the surface melts due to the high temperature caused by friction, forming a black molten shell with a thickness of about1mm. After falling into the earth, the surface of meteorites may be brown due to weathering and oxidation.
2. Except for a few meteorites, such as moon meteorites and Mars meteorites, most meteorites have different intensities of magnetism.
3. The proportion of meteorites is relatively large.
Heavier than ordinary rocks. If further identification is needed, it is recommended to send it to relevant scientific research units for professional identification such as component analysis.
There is an asteroid belt in the solar system, which lies between Jupiter and Mars. There are countless small stars in this asteroid belt, ranging in diameter from a few meters to hundreds of meters or even thousands of meters. These small stars often collide, or are attracted by other larger stars to change their orbits, and some of them fall to the earth to form meteorites.
Extended data:
The value of meteorites can be evaluated mainly from several aspects. The meteorite that people witness the falling process is called "witness meteorite", and the probability is very small, with only one case per year on average, so it is of high value.
In addition, rarity is an important factor affecting the value of meteorites. At present, about 95% of the meteorites found are stone meteorites, about 4% are iron meteorites, and there are few stone iron meteorites. The rarer the meteorite, the higher its value. There is also the appearance of meteorites. The better and more complete the appearance, the more valuable it is.
