Definition
By definition, a sphere is the locus of all points which are a fixed distance from a distinguished point.
That distinguished point is called the center of the sphere.
Linguistic Note
The British English spelling of center is centre.
The convention on $\mathsf{Pr} \infty \mathsf{fWiki}$ is to use the American English spelling center, but it is appreciated that there may be lapses.
