Traffic Report  on 21 August '13

No objects reported inside ten LD

There are no asteroids reported moving within ten lunar distances (LD) of our planet today. Coming toward Earth next, radar target 2013 QR1 arrives inside ten LD on August 25th.

This report was generated at 1512 UTC with follow-up in today's DOU MPEC for 2013 QR1 and for departed objects 2013 PR43 and radar target 277475 2005 WK4.



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.
