Object is a gray geodesic sphere 65cm in diameter consisting of sixty triangles. The areas between these triangles are empty, allowing the center of the sphere to be seen. The material the sphere is composed of is unknown. The geodesic sphere is hollow, save for the very center. At the center of SCP-123 is what appears to be a black sphere, approximately 1 mm in diameter. No light can be seen being reflecting off or emitted from the black sphere. The core also appears to exhibit significant gravitational force, which massively increases within the confines of the outer geodesic sphere. This gravitational force can be measured using sensitive instruments several dozen meters away. Within approximately three meters, the gravitational pull is apparent to any observer, with dangling objects beginning to be pulled towards the sphere. At the surface of the outer sphere, the gravitational pull doubles the weight of any object placed onto the structure.

The inner sphere’s qualities are apparent when any small object is inserted within the outer sphere. Any such object quickly accelerates into the object and disappears. Any liquid poured into the object also is sucked into the central sphere. Analysis has shown that light that nears the black sphere is curved towards the center. The amount of gravity exhibited by the inner sphere at its surface suggests that its mass is approximately 10^29 kg, though the obvious gravity reducing effect within the outer sphere means that its actual mass may actually far exceed even that. Note that such a mass would ordinarily imply a Schwartzschild radius in the order of 200 meters, way in excess of the approximate 0.5 mm actually observed, which can be considered further testament to the outer sphere's gravity dampening qualities. Gases are affected by the gravity of SCP-123, and the atmosphere pressure at its surface has been measured at 205 kPa. However, gases are unable to penetrate the area between the triangles of the outer geodesic sphere. The reason for this is currently unknown, and is currently being studied.

It should be noted that the outer sphere and inner sphere appear to act as one – whenever the outer sphere is moved, the inner sphere follows. Further research is suggested into the nature of this relationship.
