A meteorite is a space object that has passed through the earth's atmosphere and collided with a planet. Scientists and ordinary people often find fragments of these bodies. To classify them as space objects, and not as ordinary stones, it is worth knowing what a meteorite looks like. The article will discuss its distinctive features.
In iron objects, a significant specific gravity and pronounced magnetic properties are observed. Stones that have fallen a long time ago become rusty. Magnetization is also characteristic of the lion's share of stone and iron-stone bodies. In the process of moving through the atmospheric layer, the meteorite undergoes serious heating. And when it lands, it cools down, and protrusions and depressions appear on its surface. The shape of the fallen bodies resembles the head of a projectile.
It is not easy to know what a meteorite looks like in order to distinguish it, but also to carry out a reaction for nickel. This procedure is carried out at home. All that is required is to saw the sample and then polish it until it starts to shine. Then you should prepare a solution of alcohol and nitric acid in a ratio of 10 to 1 and lower the existing sample into it. If it is a meteorite element, metal crystals will be seen on its surface over time. In a stone body, they resemble grains; in an iron meteorite, they will resemble stripes.
Knowing what a meteorite looks like, one can determine by external parameters another type of these bodies - chondrites. These are small lumps of coal with small inclusions (brown) on them. As a rule, they lie in the ground for a long time, so it is difficult for an ordinary person to find them, most often specialists are engaged in this work.
After detecting a space object, it is necessary to record the following data:
place of find;
the date on which it occurred;
and so on.
It is also recommended to draw up a map of the area. If the body is fragile due to the prolonged influence of natural factors, it is necessary to take a photo and description of it, and then present the materials to professionals.
