centaur
Let an agent describe centaurs by designation, orbit, physical properties and activity, with sourced data, and separate the mythological centaur.
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 describe centaurs by designation, orbit, physical properties and activity, with sourced data, and separate the mythological centaur.
A small solar system body with an orbit between those of Jupiter and Neptune, crossing the orbits of one or more giant planets, with dynamically unstable orbits; examples include Chiron and Chariklo, which has rings.
What it is for: Studying the transition of objects from the outer solar system toward the inner planets.
It can be look up centaur orbits; compare with Kuiper belt objects and comets; find observations of activity or rings; separate the mythological sense.
Distinguishing features
Giant-planet-crossing orbits
Short dynamical lifetimes
Some are active like comets
Thought to come from the trans-Neptunian region
What it looks like
Faint points of light; some show comet-like activity.
How it is recognised
Orbits between Jupiter and Neptune
Some have comas or rings
The mythological centaur is another sense
