planetarium
Let an agent explain planetariums and how they work, relay history, technology and types from astronomy education sources, describe their educational role, and distinguish planetariums from observatories, orreries and science centres.
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 planetariums and how they work, relay history, technology and types from astronomy education sources, describe their educational role, and distinguish planetariums from observatories, orreries and science centres.
A theatre built for presenting educational and entertaining shows about astronomy and the night sky, in which a projector, historically an optical-mechanical star projector and now often a digital fulldome system, displays stars, planets and other objects on a domed ceiling, and by extension the projector itself; planetariums range from portable inflatable domes to large public and university facilities, and the word also names the orrery, a mechanical model of the solar system.
What it is for: Presenting astronomy shows.
It can be explain how they work; relay history and technology; describe educational role; distinguish related facilities.
Distinguishing features
Dome projection
Astronomy education
Optical or digital systems
Immersive shows
What it looks like
A domed theatre with a central or edge projector and reclined seating.
Physical character
first modern projector: 1923 year - Zeiss Mark I, Munich
largest domes: over 30 m - diameter
planetariums worldwide: about 4000 count - estimates
How it is recognised
Domed theatre projecting the sky
Optical-mechanical star projectors, digital fulldome planetariums, portable domes, orreries as mechanical models
Observatories house telescopes; science centres are broader; an orrery is a tabletop model
