Traffic Report  on 1 August '13

No objects reported inside ten LD

No objects are known to be traveling within ten lunar distances (LD) of our planet today. Next known to be approaching is 277475 2005 WK4, which arrives inside ten LD on August 6th.

This report was generated at 1441 UTC with follow-up in today's DOU MPEC for departed objects 2013 OY3 and 2003 DZ15.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Object distances are interpreted by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.
