The density distributions of MC orbital clones’ positions of MBA 2020 BG107 in the B-plane projection. The distribution is centered on the nominal orbit’s position of 3I (red cross in the center). The 1σ uncertainty region of the 3I’s nominal orbit is marked by red solid circle, while the maximum extension by the coma region represented by dashed red line. For simplicity, we applied the semimajor axis of uncertainty ellipsoid as a criterion and assumed the region as a sphere (circle in the current projection). The position for the nominal orbit of 2020 BG107 is shown by black dot at the upper right from the center. From performed MC analysis only 25 positions fall inside the uncertainty region of 3I (37 clones within extension by coma).
