The center of the universe would be defined in astronomical terms as the place where the Big Bang took place some thirteen and a half billion years ago. At this point in time it is probably empty. No object would still be there. Unless someone has erected a plaque, perhaps, to mark that historically important location.
An item or object that is the only one of its kind is referred to as a "unique" or "one-of-a-kind."

Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. The term centripetal force comes from the Latin words centrum ("center") and petere ("tend towards", "aim at"), signifying that the force is directed inward toward the center of curvature of the path. Isaac Newton's description was: "A centripetal force is that by which bodies are drawn or impelled, or in any way tend, towards a point as to a center."

Geocentric -- ie, the Earth is at its center.
The center of mass provides a convenient reference point for analyzing the motion of an object. It simplifies calculations related to the motion, stability, and collisions of an object by treating it as a point mass placed at the center of mass. Additionally, finding the center of mass allows for a better understanding of how forces interact with the object as a whole.
According to current scientific understanding, there is no specific object at the center of the universe. The universe is expanding in all directions from the Big Bang, and there is no central point or object.
An inverted and real image is formed by an object placed beyond the center of curvature on the principal axis of a concave mirror. The size of the image will be smaller than the object.
He had a theory that the earth revolved around the sun. Hundreds of years later, scientists proved he was right. Back then, everybody believed Aristotle and they thought the earth was at the center of the universe and everything revolved around it. Galileo kind of based his theory on that too, but it was Copernicus who thought of it.
He became a mathematician by studying math. He believed that numbers and math held the secrets of the universe. He tried to explain everything he observed with some kind of mathematical formula.
No. The earth has no unusual position, motion, structure or composition. The only feature of earth that is at all unique, based on all observations up to the present time, is that it is the only place, known so far in the universe, that harbors life of any kind. However, the discovery of life somewhere else in the universe, is a possibility that might confront us at any time.

If you are asking for a specific object then I am sorry I do not know. But I do know that any kind of mass (Cotton wool or lead) can be attracted by gravity to the center of the earth with a force of 94.3488 kg, if the object contains this amount of mass.
