## How are spheres described? |

A sphere in solid geometry is considered to be the set of points (or the “skin” of the sphere) in three-dimensional Euclidean space that are equidistant from the sphere’s singular, central point. Or, more simply, a sphere is a perfectly round, three-dimensional object. The term “sphere” also extends into other dimensions; for example, a sphere in two dimensions is also called a circle.
