Traffic Report  on 18 July '12

No objects reported inside ten LD

There are no objects reported to be within ten lunar distances (LD) of Earth today, and none are known to be approaching that close until November.

This report was generated at 0247 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.
