Because meteorites are objects from outer space, meteorites need instruments to determine whether they are true or false. The naked eye has only an auxiliary role. Most of the meteorites come from the asteroid belt between Mars and Jupiter, and a small part comes from the Moon and Mars. Meteorites can be roughly divided into stone meteorites, iron meteorites, and stone and iron mixed meteorites.

陨石的平均密度在3~3.5之间,主要成分是硅酸盐。陨铁密度为 7.5~8.0,主要由铁、镍组成。陨铁石成分介于两者之间,密度在5.5~6.0间。陨星的形状各异,最大的陨石是重1770千克的吉林1号陨石,最大的陨铁是纳米比亚的戈巴陨铁,重约60吨。中国陨铁石之冠是新疆青河县发现的“银骆驼”,约重28吨。 

The average density of meteorites is between 3 and 3.5, and the main component is silicate. The density of yttrium iron is 7.5 to 8.0, which is mainly composed of iron and nickel. The composition of yttrium iron stone is between the two, and the density is between 5.5 and 6.0. The shape of the comet is different. The largest meteorite is the 1770kg Jilin No. 1 meteorite. The largest iron ore is Namibia's Goba iron, weighing about 60 tons. The crown of Chinese iron ore is the "silver camel" discovered in Qinghe County, Xinjiang, weighing about 28 tons.


More than 40,000 samples of meteorites have been collected worldwide, with various styles. They can be roughly divided into three categories: stone meteorites(mainly composed of silicates), iron meteorites(iron-nickel alloys) and stone iron meteorites(iron and silicate mixtures).


Meteorites refer to meteorites that fall to the ground and consist of minerals such as iron, nickel, and silicate, also known as meteorites. It also refers to a meteorite that contains more or all of stone. A large number of organic substances such as ammonia, nucleic acids, fatty acids, pigments, and 11 amino acids have also been found in meteorites with high carbon content. Therefore, people think that the origin of Earth's life has a considerable relationship with meteorites.


It was observed that there is an asteroid belt between the orbits of the planets of the solar system, Mars and Jupiter. It is the hometown of meteorites. These asteroids orbit their own orbits and continue to collide. Sometimes they are knocked out of orbit and headed toward the earth. When they enter the atmosphere, the friction with them emits light and heat and is a meteor. When the meteor enters the atmosphere, the resulting high temperature, high pressure and internal imbalance will explode and a meteorite rain will form. Unburned people fall to the earth and become meteorites. People have discovered a crater 170 meters deep and 1240 meters in diameter in Arizona. There are also large craters with a diameter of 300 kilometers in Antarctica. In the middle of the Atlantic Ocean, a giant crater with a diameter of more than 1,000 kilometers was discovered.


Scientists say we accept 50,000 tons of these gifts every day. Most of them are burned out at altitudes of 10 to 40 miles above the ground and are difficult to find even on the ground. They operate in the universe. Because there is no other protection, they are directly affected by the radiation and catastrophes of various cosmic lines, and their own radioactive heating can not make it a big change. So its own records are reliable. There are considerable areas of research for it, such as high-energy physics, celestial evolution, geochemistry, and the origin of life.


At present, the largest preserved iron meteorite in the world is the Hoba iron meteorite in Namibia, Africa, weighing about 60 tons. Followed by Greenland's No. 1 iron meteorite, weighing about 33 tons. China's Xinjiang iron meteorite, weighing about 28 tons, is the world's third largest iron meteorite. The largest stone meteorite in the world is the Jilin meteorite. The total weight of the collected samples is 2,550 kilograms, and the Jilin No. 1 meteorite, weighing 1,770 kilograms, is the largest stone stone body that has been collected by humans.


In addition, there is another type of meteorite called "glass meteorite." It is black or dark green, a bit like a stone, but not a stone. It's a bit like glass, but it's a very special glassy substance without crystals. It has a variety of shapes, usually small, weighing from a few grams to dozens of grams. For the identification of glass meteorites, it mainly depends on the discovery of samples and their chemical isotope characteristics, and the chemical isotope characteristics are used as the final basis. So far, hundreds of thousands of suspected glass meteorites have been discovered, and it is strange that their distribution is obviously regional, and the cause of regional emergence has not yet been determined.
