Comparative short-term dynamical evolution of various parameters for two representative examples of orbits that are the most different from the nominal one of 2012 FC₇₁ (± 3σ deviations, see text for details). The distance from the Earth (panel A)); the value of the Hill sphere radius of the Earth, 0.0098 AU, is shown (red line). The parameter B). The orbital elements aC), eD), iE), and ωF). The distances to the descending (thick line) and ascending nodes (dotted line) appear in panel G). Earth’s aphelion and perihelion distances are also shown (red lines).
