Distribution of convergent configurations for clones of (18777) Hobson and (57738) 2001 UZ160 in Cartesian space with the following criteria: (i) physical distance ≤ 10000 km, and (ii) relative velocity ≤4 m s⁻¹. The gray histogram is a differential distribution using 10 kyr bins normalized to maximum convergent cases in a bin. The red line is a cumulative distribution. Time at abscissa extends to the past. Red vertical lines delimit median convergent time (solid), 5 and 95% levels of the cumulative distribution (dashed).
