There exists infinite spheres through n fixed linearly independent points on the n dimensional Euclidean space Rn. We shows that if one is given n linearly independent points on Rn, there exists precisely one sphere through the origin and all of the points. In this report we give a formula about the center of the sphere. This result shows that on the Euclidean space Rn an n-1 dimensional sphere passing through n+1 linearly independent points is only one.
