ABSTRACT:
An astronomical display apparatus for providing a 3-dimensional view of a plurality of scaled astronomical bodies, wherein the bodies may be elevated (to float) upon a column of air while being slowly rotated. The display apparatus includes a base having an upper, preferably flattened deck surface. The base further includes an air supply inlet tube that is coupled to air cups mounted on the deck surface to enable a source of pressurized air emitted from the air cups to form the columns of air. The apparatus may be provided with several interchangeable deck surfaces wherein each deck surface may represent a distinct collection or grouping of astronomical bodies, such as stars, planets, and or moons.
