Time evolution of the Tisserand parameter (T_J) with respect to Jupiter of QY1. T_J decreases by 0.1 over ~8000 yr, which supports that QY1 would be transported from the main-belt region. Each gray line represents different clones whose current orbital elements follow a Gaussian distribution around the average values within their standard deviations (Table 6). The black line represents the results for a particle with the average orbital elements at Epoch 2459396.5 (2021-07-01.0).
