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.
An orbital ring is a dynamically elevated ring placed around the Earth that rotates at an angular rate that is faster than orbital velocity at that altitude, stationary platforms can be supported by the excess centripetal acceleration of the super-orbiting ring (similar in principle to a Launch loop), and ground-tethers can be supported from ...
The eye-ring of a bird is a ring of tiny feathers that surrounds the orbital ring, [5] a ring of bare skin immediately surrounding a bird's eye. [5] [6] The eye-ring is often decorative, and its colour may contrast with adjoining plumage. [4] The ring of feathers is sometimes incomplete, forming an eye arc.
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 Niven ring . [ 3 ]
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.
Each orbital in an atom is characterized by a set of values of three quantum numbers n, ℓ, and m ℓ, which respectively correspond to electron's energy, its orbital angular momentum, and its orbital angular momentum projected along a chosen axis (magnetic quantum number). The orbitals with a well-defined magnetic quantum number are generally ...
Here is what the most popular diamond shapes for engagement rings mean. While reading, think about which shape reflects you and your partner. Round Brilliant Cut: Traditional and Elegant.
The capture-ejector rim is a variation that consists of a rim- or ring-shaped structure. Like a rotating skyhook, it would rotate in a direction opposite to its orbital motion, allowing a spacecraft at suborbital velocity to attach to its lower portion and later be flung into orbit from its upper portion.
