Traffic Report  on 4 August '13

No objects reported inside ten LD

There are no objects reported moving inside ten lunar distances (LD) of our planet today. Day after tomorrow 277475 2005 WK4 arrives inside ten LD.

This report was generated at 1321 UTC with follow-up in today's DOU MPEC for departed 2013 OY3 and the recovery of 277475 2005 WK4.



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.
