NOTICE: JPL's Center for NEO Studies (CNEOS), which operates neo.jpl.nasa.gov, will substantially upgrade the site in early 2017, giving it a new look-and-feel, improved navigation and added content. Scripts which extract data from HTML on the current site will have to be revised to use the related API on the new site. Specifics on the new APIs will be provided here a month before the site transition takes place.

NEO Earth Close Approaches

NEO EARTH CLOSE APPROACH TABLES

Custom tables (updated daily) showing future and past NEO close-approach data is available here:

Close-Approach Tables

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.
