2020 CD3: Temporarily Captured Object
Orbit integrations (Gray, Project Pluto; Micheli, ESA NEO Coordination
Centre; Naidu, CNEOS; and Spoto, MPC) indicate that this object is temporarily
bound to the Earth. No evidence of perturbations due to solar radiation
pressure is seen, and no link to a known artificial object has been found.
Further observations and dynamical studies are strongly encouraged.
