NEO Earth Close Approaches

NEO EARTH CLOSE APPROACH TABLES

Close-Approach Tables

Custom tables (updated daily) showing future and past NEO close-approach data, including uncertainties, are available at the link above. More information about the uncertainties used in these tables is available.

Also, a list of historic comet close approaches prior to 2006 is available here.
