Meteorites are small bodies that enter the atmosphere from outside the earth. Most of them are asteroids. However, there are also very few meteorites from the moon and Mars. Members of the family of small celestial bodies collide with each other and break up. In the age of space floating, if they come to the earth unintentionally, they will be attracted by the earth's gravity and fall to the earth first. The small ones burn up in the atmosphere, and the unburned ones fall to the ground. Meteorites turned out to be asteroids, because of the clouds, it is the study of the history of the solar system is a direct precious material.
Meteorites are rare and valuable specimens that are familiar with the solar system directly. Most meteorites carry no or unusual mineral assemblages on earth, as well as traces of rapid combustion through the atmosphere. As for the astronauts on the outer planets, such as the moon, brought back is not called meteorites. It's called moon ore. According to a 10-year inspection by Canadian scientists, there may be more than 20,000 meteorites falling to earth each year. Because the majority of meteorites fall in the sea, barren grass, forests and mountains and other areas to the desolate, and was found and network of only a few dozen pieces of meteorites every year, the number is small. Most of it falls from the sky and varies in shape.
This iron meteorite is black as a whole, the surface is not smooth, there are pores of different sizes and little distribution, the surface is full of holes and scars, and has obvious melting flow lines, melting lines, grooves, melting candle pits and other obvious characteristics. It has strong magnetism. This kind of meteorite belongs to the essence of the high-quality meteorites, weighing 1030g, and is of great value for collection and scientific research. The molten shell shines brightly in the sun. It can be described as a bright star. The surface pattern is clear and natural, lifelike, and has unparalleled precious. Meteorites have always been rare, rarer than gold.
At the same time, meteorites are not only expensive in themselves, or a very spiritual collection. These two meteorites are of great scientific value in understanding the age and evolution of the earth. Its scientific research value has exceeded the general collection of the collection, art, investment value.
