Traffic Report  on 3 August '13

No objects reported inside ten LD

No visitors are reported traveling within ten lunar distances (LD) of Earth today, but 277475 2005 WK4 arrives inside ten LD on August 6th.

This report was generated at 1415 UTC.



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.
