Artist's impression of an Orbital from the "Culture" setting of Iain M. Banks. A Bishop Ring [1] is a type of hypothetical rotating space habitat originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering. [2] The concept is a smaller scale version of the Banks Orbital, which itself is a smaller version of the ...
An orbital ring is a concept of an artificial ring placed around a body and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. For the Earth , the required speed is on the order of 10 km/sec, compared to a typical low Earth orbit velocity of 8 km/sec.
In Iain M. Banks' fictional Culture universe, an Orbital is a purpose-built space habitat forming a ring typically around 3 million km (1.9 million miles) in diameter. The rotation of the ring simulates both gravity and a day-night cycle comparable to a planetary body orbiting a star.

A space settlement (also called a space habitat, space stead, space city or space colony) is a settlement in outer space, sustaining more extensively habitation facilities in space than a general space station or spacecraft.
A Ring World is a megastructure added in the Utopia expansion, offering a solar-system sized habitat equivalent to four massive habitable planets. A Matter Decompressor is a megastructure added in the Megacorp expansion to the game and allows the owner to harvest massive amounts of minerals from the cores of Black Holes.
One of the main types of habitats of the Culture, an orbital is a ring structure orbiting a star as would a megastructure akin to a bigger Bishop ring. Unlike a ringworld or a Dyson sphere, an orbital does not enclose the star (being much too small). Like a ringworld, the orbital rotates to provide an analog of gravity on the inner surface.
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
