Dynamical evolution of one clone of 2005 TJ50 from −10 000 to 100 000 yr. From top to lower panels: semimajor axis a; eccentricity e; inclination i; 1/− 1 (k = 0) resonant angle with Saturn; argument of pericenter ω; close encounters with giant planets within three corresponding Hill radii, Jupiter (red plus), Saturn (green square), Uranus (purple cross), and Neptune (blue point).
