What are the types of meteorites?

 What is a meteorite and what are the different types?

Meteorites, interplanetary rocks that enter Earth’s atmosphere and reach the surface, are a hot topic of scientific study in the 21st century. They are composed of minerals and organic materials from outer space, and can offer scientists a glimpse into the history of the universe and of our own planet. Scientists categorize meteorites in three main types.

 

The first type of meteorite is the iron-rich meteorite. This type is composed primarily of iron and nickel, often with small amounts of other metals mixed in. Iron meteorites, also known as siderites, typically have a much higher density than other rocks, and are often seen on the surface of Earth as they have had little to no weathering. Iron meteorites are thought to have originated in the core of other planets, with their components having been blasted free by asteroid impacts or other disruptions.

 

The second type is the stony-iron meteorite, which combines elements of both the iron-rich meteorite and the stony meteorite. This type of meteorite has two distinct components, a metallic portion and a stony portion. The metallic portion consists of iron and nickel, while the stony portion may include oxides of silica, magnesium and iron. Like the iron-rich meteorites, the stony-iron ones are also thought to originate in the cores of other planets.

 

The last type is the stony meteorite, which are made up entirely of silicate minerals. These meteorites are the most common type found on Earth, and are often broken down into the two subtypes based on gas content: chondrites and achondrites. Chondrites contain gas-rich inclusions, while achondrites have no such inclusions. Stony meteorites are thought to have come from asteroids or even the surfaces of other planets.

 

In conclusion, meteorites come in three main types: iron-rich meteorites, stony-iron meteorites and stony meteorites. Each type has its own composition and its own origin story, and the study of meteorites can help scientists better understand the universe and its past.
