Traffic Report  on 10 May '12

No objects reported inside ten LD

No objects are reported passing within ten lunar distances (LD) of our planet today. Up next, 2010 KK37 arrives inside ten LD on May 15th. This report was generated at 1612 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.
