A planetarium, also known as space theatre, is the most common type of sopharium and remains the principal architectural signifier of Astronism throughout the world. According to the Astronist Institution, a planetarium can either be laic or Institutional, referring to non-religious and religious respectively.
Planetariums can be found in both rural areas, villages, towns, and in cities with a large variety of sizes, functionalities, capacities, and architectural aesthetics. All eidouraniums, grand observatories, and observatories are automatically considered to be compartmented while planetariums are the most common sopharium type to be non-compartmented due to the sheer amount of planetariums dotted around the world and the inability of The Institution to efficiently manage them all directly.
