rogue planet
Let an agent describe rogue planets by formation, detection methods, examples and uncertainties, with sourced 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 describe rogue planets by formation, detection methods, examples and uncertainties, with sourced data.
A planetary-mass object that does not orbit a star and drifts through interstellar space, either ejected from its birth system or formed alone; detected by microlensing and direct imaging in young star-forming regions.
What it is for: Understanding planet formation and galactic populations.
It can be explain how rogue planets form; describe detection methods; find notable candidates; distinguish from brown dwarfs.
Distinguishing features
Unbound to a star
Hard to detect
Possibly very numerous
Mass boundaries debated
What it looks like
Not visible to the eye; faint infrared sources or microlensing signals.
How it is recognised
No host star
Detected by microlensing or infrared imaging
Brown dwarfs are more massive
