A sphere of influence (SOI) in astrodynamics and astronomy is the oblate spheroid-shaped region where a particular celestial body exerts the main gravitational influence on an orbiting object. This is usually used to describe the areas in the Solar System where planets dominate the orbits of surrounding objects such as moons , despite the ...
In corporate terms, the sphere of influence of a business, organization, or group can show its power and influence in the decisions of other businesses/organizations/groups. The influence shows in several ways, such as in size, frequency of visits, etc. In most cases, a company described as "bigger" has a larger sphere of influence.
The simplification is achieved by dividing space into various parts by assigning each of the n bodies (e.g. the Sun, planets, moons) its own sphere of influence.When the spacecraft is within the sphere of influence of a smaller body, only the gravitational force between the spacecraft and that smaller body is considered, otherwise the gravitational force between the spacecraft and the larger ...
At this density, the settlement's population, spheres of influence, and gross domestic product tends to exceed that of most countries with lesser density. The need for administrative divisions , public transportation , public infrastructure and other government public services is critically essential for the sustainable growth and continued ...

Escape velocity calculations are typically used to determine whether an object will remain in the gravitational sphere of influence of a given body. For example, in solar system exploration it is useful to know whether a probe will continue to orbit the Earth or escape to a heliocentric orbit.
The gravity model can also be used to determine the sphere of influence of each central place by estimating where the breaking point between the two settlements will be. An example of this is the point at which customers find it preferable, because of distance, time and expense considerations, to travel to one center rather than the other.
First important concept is "gravity balancing motion" near the perturber and for the background as a whole ¯ (), by consistently omitting all factors of unity , , etc for clarity, approximating the combined mass + and being ambiguous whether the geometry of the system is a thin/thick gas/stellar disk or a (non)-uniform stellar/dark sphere ...
