The structure of meteorites and their distinguishing features

In fact, the composition and structure of meteorites form certain features, characteristics and properties. What are they? The structure of meteorites In fact, the structure of extraterrestrial bodies that have reached us differs from each other.

Depending on the structural features, the following types of meteorites are distinguished:

Differentiated (achondrites, iron and iron-stone) – an extensive group that includes fragments or parts of space objects of asteroid or planetary size. Moreover, their substance underwent division into constituent elements, i.e. differentiated. Of course, they are of special interest. Since they reflect where and how the structure of celestial bodies is formed.

Undifferentiated (chondrites) have not undergone substance differentiation.

As already mentioned, they appeared directly from the protoplanetary cloud. In addition to whole formations, sometimes only fragments are found. However, even one meteorite piece can tell a lot about it. Thanks to study and many studies, it was found out that the structure of meteorites is crystalline, and very small, tiny. It has a rather complex structure and is characterized by high density.

Organics of celestial bodies that fell to Earth According to scientists

organic substances are present in these celestial objects, which may be of biogenic nature. Which indicates the possibility of the existence of extraterrestrial life. However, let’s repeat once again, it is only possible. There is a possibility of synthesis of substances contained abiogenically, that is, not by biological means. To put it briefly, the organic matter in meteorites is represented by saturated and aromatic hydrocarbons, carboxylic acids and nitrogenous compounds.

By the way, hydrocarbon representatives of space have a melting crust that serves as a heat insulator. As a result, a significant part of the material is preserved practically unchanged. And this allows to more fully study their composition and structure. Of course, the proportion of organic matter found on the objects is not as high as, for example, iron or silicates. But still she is. Some signs of a meteorite In fact, distinguishing features of meteorite bodies are melting crust, regmalipts and magnetism.

The term “sclott” is used to describe a type of skin condition

That is characterized by the development of small, raised bumps on the skin. These bumps may be red, white, or both, and are often itchy and/or painful. Sclott can affect any area of the body, but is most commonly seen on the face, neck, chest, and back. In some cases, sclott may also lead to the development of blisters. Sclott is thought to be caused by a number of factors, including genetics, allergies, and exposure to certain chemicals or irritants. Treatment for sclott typically involves the use of topical corticosteroids and/or oral antihistamines.

 What is crust melting, in principle, is roughly clear from the name.

It is worth noting that this layer, which covers all substances, is formed when it enters the Earth’s atmosphere. As the body is heated, the temperature can reach 18,000 °C. Strictly speaking, the melting crust is a thin shell of meteoric matter that melts and then solidifies. In most cases, it has a matte black surface. Although the substance is lighter inside. But regmalipts are small depressions that arise as a result of the vaporization of a flammable, highly heated substance. That is, they also appear on the surface of meteorites when passing through the atmospheric layers of the planet. In addition to everything, meteorite objects have magnetic properties.

This is mainly due to the chemical composition.

Because they contain nickel iron to one degree or another. Which can be said to be a strong magnetic substance. By the way, it can be magnetized even under the influence of a weak electromagnetic field. Therefore, the state of the meteorite in the air and on the surface changes somewhat. Because during the flight, thermal changes occur with it both inside and outside. And after falling, or rather approaching the earth’s crust, they cool down. Thus, it can be said that the features of meteorite bodies formed when they hit the .
