Notes. Only the results for HIP 981 are from a three-body calculation; see text for the explanation. The star HIP 21553 is additionally added since its minimum distance is only slightly over 1 pc and it has a small relative velocity. The nominal orbit of ’Oumuamua and nominal stellar data are used for the results presented inCols. 2–5. In the last column we show the minimum proximity distance variation interval obtained from the 10 000 clones of ’Oumuamua.
