Top left panel: mean geocentric corotating Cartesian y and x coordinates of 2020 CD₃ orbital clones ±5 yr centered on 2020 March 23 UTC encompassing its ∼700 day capture completing ∼five revolutions around the Earth–Moon system. The red dotted line indicates the trajectory of 2020 CD₃ before 2020 March 23 UTC, and the blue dotted line indicates the trajectory of 2020 CD₃ after 2020 March 23 UTC. A green circle with a radius of three times the Earth’s Hill radii of ∼0.03 au is overplotted. The direction toward the Sun in the corotating frame is indicated. Top right panel: same as the top left panel except for mean geocentric corotating Cartesian x and z coordinates. Bottom left panel: evolution of 2020 CD₃’s orbital clones’ mean semimajor axes ±5 yr centered on 2020 March 23 UTC. The color code of the dotted lines is the same as in the top panels. Bottom right panel: mean geocentric distance of 2020 CD₃ orbital clones ±5 yr centered on 2020 March 23 UTC. A horizontal green line indicates three times the Hill radii in distance. The color code of the dotted lines is the same as in the previous three panels.
