A locus of points is just the set of points satisfying a given condition. The locus of points equidistant from a point is a circle, since a circle is just a set of points which are all the same distance away from the center
the set of points equidistant from a fixed point
You can define a circle as the locus (set) of all points equidistant from a given point.
sphere
The set of all points in the plane equidistant from one point in the plane is named a parabola.
equidistant, the circumference of a circle is formed by equidistant points from the center of the circle. It could also be the surface of a sphere if you are not limited to two dimensions.
