Orbital evolution calculations of the 2023 RN3 nominal orbit and 100 clones. Top panel: semimajor axis a vs. date. The red dashed line indicates the starting epoch of the orbital integrations. The y-axis range of the top panel has been chosen to clearly show the small jumps in a near the current epoch. Middle and bottom panels: as for the top panel, but showing eccentricity e and perihelion distance q.
