What it is Filled
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.
Why it exists Filled
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.
Distinguishing features Filled
- Survives atmospheric entry
- Fusion crust
- Stony, iron or stony-iron
- Solar System record
What robots and AI may and may not do Filled
Must not
- Declare a rock to be a meteorite without expert classification.
- Help sell or export meteorites in breach of the laws of the country where they fell.
- Collect meteorites from protected land or another person's property without permission.
- Present fake or misclassified specimens as authentic in a sale.
Only with a human decision
- Removing a meteorite from the site where it fell.
- Selling, donating or cutting a meteorite of scientific value.
May
- Describe meteorite types and how they differ from meteors and meteoroids.
- Refer a suspected meteorite to a qualified museum or laboratory for classification.
- Report a fall or find to the authority that records meteorites where the finder agrees.
Moral aspects Filled
- Meteorites are scientific heritage, and many countries treat them as public property.
- A market in meteorites invites fraud and the looting of fall sites.
Who is affected
- Landowners and finders
- Scientists and museums
- Buyers of specimens
Owners Filled
Steward
The owner of the land where it fell, or the state where the law claims meteorites.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.meteorite
- Wikidata: Q60186 (https://www.wikidata.org/wiki/Q60186)
Direct properties required Filled
- types: stony, iron, stony-iron list
- fusion crust: from atmospheric heating note
- registry parents: astronomical object, rock note
Recognition required Filled
- Extraterrestrial rock or metal that lands

- A meteoroid is in space; a meteor is the light streak; a comet is an icy body; terrestrial rocks are earthly
- Rocky or metallic fragments, often with a dark fusion crust from atmospheric heating.
