Traffic Report  on 9 June '12

One object reported inside ten LD

One object is reported passing within ten lunar distances (LD) of our planet today. 2012 LA is outbound from 9.08 to 9.32 LD. No other objects are known to come inside ten LD until November.

This report was generated at 1727 UTC with follow-up in today's DOU MPEC for 2012 LA.


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.
