Amor asteroid
Let an agent describe Amor asteroids by designation, orbit, size and official risk assessment, separating them from Earth-crossing groups.
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 Amor asteroids by designation, orbit, size and official risk assessment, separating them from Earth-crossing groups.
A group of near-Earth asteroids whose orbits approach but do not cross Earth orbit from outside, with perihelion distances between about 1.017 and 1.3 au; named after 1221 Amor, and including 433 Eros.
What it is for: Planetary defence, science and mission targets.
It can be look up orbits and close approaches; distinguish Amors from Apollos and Atens; find mission data such as for Eros; check official risk information.
Distinguishing features
Earth-approaching, not crossing
Many are Mars-crossers
Orbits can evolve
Include mission targets
What it looks like
Faint moving points in telescopes; some imaged by spacecraft.
