Distribution of average durations of temporary captures by Jupiter. Upper panel: for 2020 MK₄, 29P/Schwassmann-Wachmann 1 (second to upper panel), P/2008 CL94 (Lemmon) (second to bottom panel), and P/2010 TO20 (LINEAR-Grauer) (bottom panel). Median values are displayed as vertical green lines. The bins were computed using the Freedman and Diaconis rule implemented in NumPy (van der Walt et al. 2011; Harris et al. 2020). In the histogram, we use counts to form a probability density so the area under the histogram will sum to one.
