meteoritiilmiöitä

Meteoritiilmiöitä refers to phenomena associated with meteorites. A meteorite is a solid piece of debris from an object, typically a comet or asteroid, that originates in outer space and survives its passage through the Earth's atmosphere to reach the surface. The journey of a meteorite through the atmosphere is known as a meteor or shooting star.

When a meteoroid enters Earth's atmosphere at high speed, it experiences friction and compression, causing it to heat up and glow. This visible streak of light is the meteor. If the object is large enough, it may not completely vaporize and can reach the Earth's surface as a meteorite. The impact of a meteorite can create a crater, the size of which depends on the meteorite's mass, velocity, and the composition of the ground it strikes.

The study of meteorites provides valuable insights into the composition and early history of the solar system, as they are remnants from the formation of planets. Different types of meteorites exist, including stony meteorites, iron meteorites, and stony-iron meteorites, each offering clues about the celestial bodies from which they originated. Meteorite falls are observed events, while meteorite finds are objects discovered on Earth that are determined to be extraterrestrial in origin. Observing and collecting meteorites is a significant aspect of planetary science and astronomy.
