NWA 7397 Martian meteorite, Martian shergottite

NWA 7397 Martian meteorite

This is an authentic fragment of NWA 7397, a meteorite from Mars. This meteorite was found in Northwest Africa in 2012 and is classified as a Martian shergottite.

Rocks from the red planet

Martian meteorites are among the most fascinating meteorites found on Earth. They originated from rocks from Mars that were hurled into space by a massive impact. After a long journey through the solar system, a small portion of that material eventually landed on Earth.

For collectors

A real piece of Mars immediately captures the imagination. NWA 7397 is therefore a special collector's item for anyone seeking not only a meteorite, but also a tangible connection to another planet. The fragment comes in the collector's box shown.

What is a meteorite?

A meteorite begins as a meteoroid: a small piece of rock or metal moving through space. As soon as such an object enters the Earth's atmosphere, compression and heating of the air create a bright light phenomenon that we call a meteor or fireball. Only the part that survives this passage and actually reaches the ground is called a meteorite. During flight, a dark, thin molten crust often forms on the outside. Many meteorites break apart into multiple pieces along the way, creating a so-called strewn field. The speed upon entry is often many kilometers per second higher than the final speed upon impact at the Earth's surface, because the atmosphere strongly slows the object down.

Classification and origin

Meteorites are classified based on their composition and internal structure. Most discovered meteorites are chondrites: stony meteorites with small spherical inclusions, known as chondrules, which belong to the oldest solid material from the early solar system. In addition, there are achondrites, which lack these chondrules and originate from celestial bodies where geological processes such as melting and crystallization have already taken place. Examples of these are eucrites from the HED group, which are associated with the asteroid Vesta. The letters and numbers in classifications such as H6, L5-6, or LL4 provide information about, among other things, the iron content and the degree of thermal change in the parent material. As a result, a classification reveals something not only about the type of meteorite but also about its geological history.
