What does aerolite mean?
An aerolite is a stony meteorite: a natural mass of rock that has travelled through space and fallen onto the Earth's surface. The word combines the Greek-derived element 'aero-', meaning air, with '-lite', meaning stone, and was coined in the early nineteenth century as scientists began classifying fallen celestial material. Aerolites are distinguished from siderites, which are composed chiefly of iron and nickel; most falls of this kind are indeed stony rather than metallic. In contemporary usage the term has largely been superseded by 'meteorite' and its subdivisions such as chondrite and achondrite, so it now appears mostly in older scientific texts, museum catalogues, and historical narratives of famous falls. Nevertheless, it remains a precise and evocative word, useful for describing the dramatic moment when rock from space arrives on Earth, and it carries connotations of rarity, antiquity, and scientific wonder.
nounA stony meteorite — a mass of stone or rock that has fallen to Earth from outer space.
- A stony meteorite; a piece of rock from space that has fallen to Earth.
"The museum's newest acquisition is an aerolite that landed in the Australian outback in 1969."
"Farmers in the village were astonished when an aerolite crashed through the roof of their barn."
"Chemical analysis of the aerolite revealed minerals found nowhere else on Earth."
Standard pluralization; used when referring to multiple fallen stones or to the class of stony meteorites generally.
"Several aerolites were recovered from the desert impact site."
Before scientists agreed on what they were, aerolites were dismissed by learned societies as 'thunderstones' — rocks that couldn't possibly fall from the sky.

Etymology of aerolite
The word aerolite derives from the Greek elements 'aer' (air) and 'lithos' (stone), joined in the early nineteenth century as European science began formally studying stones fallen from the sky. It belongs to the same family as other 'aero-' words borrowed from Greek, such as aerial, aerosol, and aeronautics. Its use peaked during the Victorian era of meteor classification, after which 'meteorite' became the standard scientific term.

How aerolite is actually used
Aerolite is a somewhat dated and technical term; modern scientific writing overwhelmingly uses 'meteorite' or 'stony meteorite' instead. It survives mainly in older literature, mineralogy collections, and historical accounts of meteor falls.
Easily confused with aerolite
Meteorite is the general term for any extraterrestrial object that reaches Earth's surface, while aerolite specifically denotes the stony variety as opposed to metallic ones (siderites).
Aerolith is simply an older variant spelling of the same word, not a different term.
