Rama (spacecraft)
Rama is a fictional mysterious extraterrestrial vessel that is the subject and setting of the science fiction novel ''Rendezvous with Rama'' by Arthur C. Clarke, and the later sequel trilogy by Clarke and Gentry Lee: ''Rama II'', ''Garden of Rama'', and ''Rama Revealed''. It exists in a fictional future timeline of Earth. In the books Rama is described by Clarke as essentially a dark, featureless metallic cylinder distinguished by its size: 54 km long and 20 km in diameter. If the cylinder were unfolded, its internal area would be 50 km long and 50 km wide, giving a surface area of 2500 km2. The cylinder is described as being mostly hollow and, when rotating around its long axis, creates the illusion of gravity on the inner surface of the shell in the style of an O'Neill cylinder. The characters experience the Coriolis effect at various points in the novel when objects are not in contact with the hull. Rama is, for all intents and purposes, an artificial world, with a usable landscape, capable of supporting human life. It belongs to the science-fiction class of Big Dumb Objects.
