Let an agent explain natural satellites, relay types, formation, notable moons and the status of exomoons from planetary science sources with counts checked against current data, describe the named forms, and distinguish natural satellites from planets, dwarf planets, artificial satellites, ring particles and quasi-satellites.

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 explain natural satellites, relay types, formation, notable moons and the status of exomoons from planetary science sources with counts checked against current data, describe the named forms, and distinguish natural satellites from planets, dwarf planets, artificial satellites, ring particles and quasi-satellites.

A celestial body that orbits a planet, dwarf planet or smaller body, also called a moon, ranging from large moons such as Ganymede and Titan, bigger than Mercury, to tiny irregular moonlets; forms the registry aliases name include regular moons on close circular orbits formed with their planet, planetary moons in general, co-orbital moons sharing an orbit, and exomoons or extrasolar moons around planets of other stars, which remain unconfirmed, along with claimed moons of Earth, historical or quasi-satellite claims that are not true moons. The Solar System has hundreds of known moons, and counts change as surveys continue, so figures should be checked against current sources.

What it is for: Bodies orbiting planets and smaller objects.

It can be explain types and formation; relay notable moons; describe named forms; relay exomoon status with attribution.

Distinguishing features

Orbits a planet or body

Regular or irregular orbits

Varied sizes

Exomoons unconfirmed

What it looks like

Rocky or icy bodies orbiting planets, from spherical worlds to irregular lumps.

Physical character

largest moon: Ganymede note - larger than Mercury

known Solar System moons: hundreds count - check current

confirmed exomoons: none firmly confirmed note - check current

How it is recognised

Body orbiting a planet or smaller body

Co-orbital moon, extrasolar moon, claimed moons of Earth, unconfirmed extrasolar moon, regular moon, planetary moon

Planets orbit the Sun; dwarf planets are smaller; artificial satellites are made; ring particles are tiny; quasi-satellites only appear to orbit a planet

What the second pass must settle

  • How should moon counts be kept current?
  • Should candidate exomoons be flagged as unconfirmed?
  • Should co-orbital moons be a separate entry?
