meteoroid
Let an agent handle meteoroids, meteors and meteorites with correct terms, observation guidance and reporting routes.
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 handle meteoroids, meteors and meteorites with correct terms, observation guidance and reporting routes.
A small rocky or metallic body travelling through space, much smaller than an asteroid (roughly under 1 m); when it enters the atmosphere it produces a meteor, and any surviving fragment is a meteorite.
What it is for: Meteoroids reveal the Solar System composition and cause meteor showers.
It can be watch meteor showers; report fireballs; study recovered meteorites; protect spacecraft from micrometeoroids.
Distinguishing features
Small body in space
Meteor is the light phenomenon
Meteorite is the surviving fragment
Streams cause meteor showers
What it looks like
Invisible in space; seen as meteors (shooting stars) in the atmosphere.
Physical character
size: about 30 micrometres to 1 m - IAU usage
entry speed: 11-72 km/s
How it is recognised
Meteors streaking across the sky
Fireballs brighter than Venus
Micrometeoroids are dust-sized
