METEORITES Meaning and
Definition
-
Meteorites are celestial objects that fall to the Earth's surface from outer space. These solid fragments originate from bodies such as asteroids, comets, or even the Moon and Mars. Traveling through the atmosphere, meteoroids – the name given to these objects before atmospheric entry – experience intense heat, friction, and pressure, causing them to heat up and produce a luminous trail known as a meteor or shooting star. However, if the meteoroid survives the journey without completely burning up, it reaches the Earth's surface as a meteorite.
Meteorites can vary in size, shape, and composition, and are classified into three main types: stony, iron, or stony-iron meteorites. Stony meteorites are composed mostly of rocky material, while iron meteorites consist primarily of iron and nickel. Stony-iron meteorites are a combination of both rocky and metallic components. The study of meteorites, known as meteoritics, provides valuable insights into the formation and evolution of the solar system, as they are remnants from its early stages.
Investigating meteorites can yield important scientific information, such as their age, mineralogy, chemical composition, and isotopic composition. These findings help scientists understand the processes that occurred during the formation of the solar system and shed light on the geological history of celestial bodies. Additionally, meteorites can contain organic compounds, such as amino acids, which are the building blocks of life, making them important in the study of astrobiology and the potential origins of life on other planets.

Etymology of METEORITES
The word "meteorite" derives from the Greek roots "meteoron" meaning "thing in the sky" and "-ites", which denotes a rock or mineral. The term "meteoron" itself comes from the Greek word "meteoros" meaning "high in the air" or "suspended". The original usage referred to any celestial phenomenon, including atmospheric phenomena like clouds or meteors. Later, as scientific understanding progressed, the term became specifically associated with extraterrestrial rocks that have fallen to Earth after passing through the atmosphere, which we now know as meteorites.
