planetary system
Let an agent handle planetary systems by host star, members, architecture, discovery method and habitability, with sourced catalogue data.
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 planetary systems by host star, members, architecture, discovery method and habitability, with sourced catalogue data.
A set of gravitationally bound non-stellar objects, such as planets, dwarf planets, moons, asteroids and comets, orbiting a star or star system; the Solar System is one example, and thousands of exoplanet systems are known.
What it is for: Understanding planets and their origins.
It can be list known planets of a system; compare system architectures; explain detection methods; discuss habitable zones with sources.
Distinguishing features
Bound to a star
Diverse architectures
Mostly detected indirectly
Formed from protoplanetary disks
What it looks like
A star with orbiting planets; mostly known from indirect measurements.
How it is recognised
Host star and planet designations such as b, c, d
Detection by transit, radial velocity or imaging
Star clusters are not planetary systems

- How should candidate status be shown?
