Cordelia (kor-dee'-lee-a) is the innermost moon of Uranus. Apart from its orbital radius and dimensions, virtually nothing is known about it. It takes its name from the youngest daughter of Lear in William Shakespeare's King Lear. http://www. ... Richard J.

In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity. ... In classical geometry, a radius of a circle or sphere is any line segment with one endpoint on the circle (i. ... A kilometre (American spelling: kilometer, symbol: km) is a unit of length equal to 1000 metres (from the Greek words khilia = thousand and metro = count/measure). ... In astrodynamics, under standard assumptions any orbit must be of conic section shape. ... The orbital period is the time it takes a planet (or another object) to make one full orbit. ... Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees. ...

This article explains the meaning of area as a physical quantity. ... Square kilometre (US spelling: Square kilometer), symbol km², is an SI unit of surface area. ... Volume, also called capacity, is a quantification of how much space an object occupies. ... A cubic kilometre (symbol km³) is an SI derived unit of volume. ... Mass is a property of physical objects that, roughly speaking, measures the amount of matter they contain. ...

Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. ... It has been suggested that Law of universal gravitation be merged into this article or section. ... Acceleration is the time rate of change of velocity, and at any point on a v-t graph, it is given by the gradient of the tangent to that point In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. ... In physics, for a given gravitational field and a given position, the escape velocity is the minimum speed an object without propulsion, at that position, needs to have to move away indefinitely from the source of the field, as opposed to falling back or staying in an orbit within a... On a prograde planet like the Earth, the sidereal day is shorter than the solar day. ... Axial tilt is an astronomical term regarding the inclination angle of a planets rotational axis in relation to its orbital plane. ... The albedo is a measure of reflectivity of a surface or body. ... Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ...

Cordelia acts as the inner shepherd satellite for Uranus' epsilon ring. Cordelia's orbit is within Uranus' synchronous orbit radius, and is therefore slowly decaying due to tidal forces. A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. ... A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. ... The tidal force is a secondary effect of the force of gravity and is responsible for the tides. ...
