LUNAR METEORITES Meaning and
Definition
-
Lunar meteorites can be defined as meteorites that originate from the Moon. These are fragments or rocks that were ejected off the lunar surface due to impacts from other celestial bodies, such as asteroids or comets, and traveled through space before landing on Earth.
As extraterrestrial objects, lunar meteorites preserve crucial information about the Moon's geology and history. They provide scientists with a unique opportunity to study lunar material without the need for expensive and challenging manned missions. Additionally, lunar meteorites offer insights into the broader understanding of the solar system's evolution and the processes that shaped our celestial neighborhood.
Lunar meteorites are classified into different types based on their characteristics, including basaltic, breccia, and anorthositic varieties. Basaltic lunar meteorites primarily consist of dark igneous rock formed from solidified lava flows on the lunar surface. Breccia lunar meteorites are made up of fragments of various sizes and types of lunar rocks that were crushed and fused together by the force of impact events on the Moon. Lastly, anorthositic lunar meteorites mostly contain a plagioclase feldspar mineral called Anorthosite, which forms a prominent part of the Moon's crust.
When lunar meteorites land on Earth, they are typically found in remote and desolate locations like Antarctica or deserts where their dark, sometimes black, appearance contrasts with the surrounding environment. Collecting and analyzing lunar meteorites not only improves our knowledge of the Moon's composition and geological history but also enhances our understanding of the origins and dynamics of the solar system as a whole.
Etymology of LUNAR METEORITES
The word "lunar" originates from the Latin word "luna", which means "moon". It is derived from the ancient Roman goddess of the moon, also named Luna. "Lunar" is used to describe anything related to the moon.
The word "meteorite" has its origins in the Greek language. "Meteoron" means "high in the air", and "meteoros" means "suspended in the air" or "raised from the ground". Over time, the word evolved to describe the phenomena seen in the sky, including shooting stars and meteors. "Meteorite" specifically refers to the remains of a meteoroid that survives its passage through the Earth's atmosphere and lands on the surface.
Therefore, the term "lunar meteorites" combines the words "lunar" (related to the moon) and "meteorites" (remains of extraterrestrial objects that have fallen to Earth).
