The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.
Chondrites are stony (non-metallic) meteorites that have not been modified due to melting or differentiation of the parent body.
Chromite is an iron chromium oxide: FeCr2O4.
Fayalite (Fe2SiO4; commonly abbreviated to Fa), also called iron chrysolite, is the iron-rich end-member of the olivine solid-solution series.
Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.
The Flora or Florian '''family''' of asteroids is a large grouping of S-type asteroids in the inner main belt, whose origin and properties are relatively poorly understood at present.
This is a glossary of terms used in meteoritics, the science of meteorites.
The H type ordinary chondrites are the most common type of meteorite, accounting for approximately 40% of all those catalogued, 46% of the ordinary chondrites, and 44% of the chondrites.
Hypersthene is a common rock-forming inosilicate mineral belonging to the group of orthorhombic pyroxenes.
An iron–nickel alloy or nickel–iron alloy, abbreviated FeNi or NiFe, is a group of alloys consisting primarily of the elements nickel (Ni) and iron (Fe).
The LL chondrites are a group of stony meteorites, the least abundant group of the ordinary chondrites, accounting for about 10–11% of observed ordinary-chondrite falls and 8–9% of all meteorite falls (see meteorite fall statistics).
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
Meteoritics & Planetary Science is a monthly peer-reviewed scientific journal that was established in 1953.
The mineral olivine is a magnesium iron silicate with the formula (Mg2+, Fe2+)2SiO4.
The ordinary chondrites (sometimes called the O chondrites) are a class of stony chondritic meteorites.
The Ordovician meteor event was a dramatic increase in the rate at which L chondrite meteorites fell to Earth during the Middle Ordovician period, about 467.5 million years ago.
A phosphate is chemical derivative of phosphoric acid.
The pyroxenes (commonly abbreviated to Px) are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
S-type asteroids are asteroids with a spectral type that is indicative of a silicaceous (i.e. stony) mineralogical composition, hence the name.
Troilite is a rare iron sulfide mineral with the simple formula of FeS.
433 Eros, provisional designation, is a stony and elongated asteroid of the Amor group and the first discovered and second-largest near-Earth object with a mean-diameter of approximately 16.8 kilometers.
8 Flora is a large, bright main-belt asteroid.
