orbit
Let an agent explain orbits by physics, elements, types and applications in astronomy and spaceflight, including space debris and sustainability.
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 orbits by physics, elements, types and applications in astronomy and spaceflight, including space debris and sustainability.
The curved path of an object around a star, planet or other body under gravity, usually approximated by an ellipse as described by Kepler laws, and characterised by orbital elements; types include low Earth, geostationary, polar, sun-synchronous, retrograde and halo orbits around Lagrange points.
What it is for: Astronomy, spaceflight and satellite services.
It can be explain Kepler laws and orbital elements; classify satellite orbits; find orbital data for objects; understand space debris issues.
Distinguishing features
Gravity-bound path
Described by orbital elements
Periodic for bound orbits
Many practical types
What it looks like
Not visible as a line; shown in diagrams, satellite tracks and planetary motions.
How it is recognised
Ellipses around a central body
Satellite ground tracks
Suborbital flights do not complete an orbit
