SCP-225-1 and SCP-225-2 are shiny gray metallic spheres of unknown origin and composition, each with a diameter of 0.681 meters.
SCP-225-1 appears stable and motionless, but is in fact moving in a geosynchronous path above Earth, at the exact speed of Earth's rotation, maintaining its relative position at all times. Gravity, magnetism, and all other forces tested have had no effect upon it; it maintains position approximately 7.3 meters above the surface. No amount of force brought to bear on it in any direction has any effect upon its position; all tools and weaponry tested have no effect upon it physically.
SCP-225-2 follows a path around the sun that is nearly synchronous with Earth's. It does not orbit Earth; Earth rotates under it, giving it the illusory appearance of traveling around the Earth at velocities usually ranging from 1,600 - 2,000 km/h, depending on its current relative altitude. It does not technically orbit the sun either; it appears to be moving under its own power via unknown means. Its course has not been entirely predictable.
Similarly to SCP-225-1, no force or weaponry brought to bear upon it has had any effect, though testing on it is significantly more difficult, time-consuming, and resource-intensive due to the variation in its relative position.
