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 ...
The Hill sphere is a common model for the calculation of a gravitational sphere of influence. It is the most commonly used model to calculate the spatial extent of gravitational influence of an astronomical body (m) in which it dominates over the gravitational influence of other bodies, particularly a primary (M).

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.

An influence diagram (ID) (also called a relevance diagram, decision diagram or a decision network) is a compact graphical and mathematical representation of a decision situation. It is a generalization of a Bayesian network , in which not only probabilistic inference problems but also decision making problems (following the maximum expected ...
Obama is gearing up to increase his sphere of influence — and potentially his net worth — as a producer. He and Michelle Obama signed a deal to produce series and films for Netflix in 2018.
CEO Elon Musk’s big bet on a Trump win, and the resulting influence he is seen as having on the new administration, has investors bullish on Tesla’s prospects. Tesla stock closed at $424.77 ...
The size of the "neighborhoods" (or spheres of influence) vary with radius : r S O I = a p ( m p m s ) 2 / 5 {\displaystyle r_{SOI}=a_{p}\left({\frac {m_{p}}{m_{s}}}\right)^{2/5}} where a p {\displaystyle a_{p}} is the semimajor axis of the planet's orbit relative to the Sun ; m p {\displaystyle m_{p}} and m s {\displaystyle m_{s}} are the ...
