meteorite
Let an agent explain meteorites, relay types, origins, scientific value and collection law from planetary science sources, describe the named types, and distinguish a meteorite from a meteoroid, a meteor, a comet and an ordinary terrestrial rock.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain meteorites, relay types, origins, scientific value and collection law from planetary science sources, describe the named types, and distinguish a meteorite from a meteoroid, a meteor, a comet and an ordinary terrestrial rock.
A solid fragment of rock or metal from an asteroid, comet, the Moon or Mars that survives passage through the atmosphere and lands on a surface, with types the registry aliases name such as stony chondrites including CR, CK and CB carbonaceous chondrites, asteroidal meteorites and tiny micrometeorites; a meteorite differs from a meteoroid in space and a meteor, the streak of light as it burns. Meteorites are studied for the history of the Solar System, are collected and traded under laws that vary by country, and freshly fallen meteorites should be handled and reported per scientific and legal guidance.
What it is for: Extraterrestrial rock or metal reaching a surface.
It can be explain types and origins; relay scientific value; relay collection law; distinguish related terms.
Distinguishing features
Survives atmospheric entry
Fusion crust
Stony, iron or stony-iron
Solar System record
What it looks like
Rocky or metallic fragments, often with a dark fusion crust from atmospheric heating.
Physical character
types: stony, iron, stony-iron list
fusion crust: from atmospheric heating note
registry parents: astronomical object, rock note
How it is recognised
Extraterrestrial rock or metal that lands
CR chondrite, CK chondrite, CB chondrite, asteroidal meteorite, strewn-field-producing meteorite, micrometeorite
A meteoroid is in space; a meteor is the light streak; a comet is an icy body; terrestrial rocks are earthly
