Short-term evolution and capture episode of 2024 PT₅. The left panels show the evolution of the values of the relevant parameters over the time interval (−150, 150) yr. The right panels focus on the time window (−1.0, 1.0) yr around the current epoch (2460600.5 TDB, 2024-Oct.-17.0). Top: time evolution of the relative mean longitude. Middle: Time evolution of the geocentric energy that focuses on negative values. Bottom: Time evolution of the geocentric distance for values under 0.03 au. The evolution of the nominal orbit is shown in black, those of the control orbits with state vectors separated ±3σ from the nominal ones in lime–green, ±6σ in cyan–blue, and ±9σ in fuchsia–crimson. The unit of energy is such that the units of mass, distance, and time are 1 M_⊙, 1 au, and one sidereal year divided by 2π, respectively. The output interval is 0.36525 d.
