Distribution of minimum approach distances. Upper panel: for the pair 29P/Schwassmann-Wachmann 1 and 2020 MK4. Middle panel: for the pair P/2008 CL94 (Lemmon) and 2020 MK4. Bottom panel: for the pair P/2010 TO20 (LINEAR-Grauer) and 2020 MK4. 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.
