Meteorites are fragments of small celestial bodies that roamed through space, unable to grow into planets, and were broken apart. These fragments are pulled into Earth's gravitational field and subjected to frictional heat from the atmosphere. Despite this, some manage to survive and reach the Earth's surface without completely burning up. Earth collides with over 100 million extraterrestrial objects every day, bringing in more than 100 tons of meteorites. However, the vast majority (about 90%) are less than 1 millimeter in diameter and almost all burn up upon entering the atmosphere. It is extremely rare for meteorites to pass through the atmosphere and reach the surface. Konronsha has a collection of several hundred meteorites, including large ones weighing up to 100 kg.
