Traffic Report  on 3 August '12

No objects reported inside ten LD

No asteroids are reported to be within ten lunar distances (LD) of Earth today, and none are known to be coming that close until November. This report was generated at 1442 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.
