Notes. Stars are sorted here by the proximity distance. To speed up the selection procedure, the motion of each object was traced individually as a three-body problem under the influence of the full Galactic potential. For its nominal orbit, we recorded the minimum ’Oumuamua – star distance (Min dist), moment of this approach (Epoch), relative velocity (V rel), and heliocentric distance of the approach (r_hel). A proximity epoch equalling zero means that the star’s closest position was at the beginning of the backward numerical integration when ’Oumuamua was at 250 AU from the Sun.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
