Evolution over time of orbital elements and other relevant parameters for the nominal orbit of 2023 DZ₂ (see Table 1). The top panel shows the evolution of the geocentric distance; the value of the Hill radius of the Earth, 0.0098 au, is plotted as reference. The second to top panel focuses on the evolution of the value of the Kozai–Lidov parameter. The following four panels show the evolution of the values of semi-major axis, eccentricity, inclination, and argument of perihelion of the nominal orbit. The bottom panel displays the distances from the descending (thick line) and ascending nodes (dotted line) to the Sun; Earth’s aphelion and perihelion distances are shown in red. The output time-step size is 0.1 yr. The source of the input data is JPL SBDB. The standard epoch JD 2460000.5 (25 February 2023) TDB, which is the origin of times.
