Traffic Report  on 4 September '12

No objects reported inside ten LD

No asteroids are reported traveling inside ten lunar distances (LD) of our planet today. Approaching our neighborhood next, radar target 2012 QG42 arrives inside ten LD on September 11th and 2010 JK1 on November 22nd.

This report was generated at 1547 UTC with follow-up in today's DOU MPEC for 2012 QG42.


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.

NEOCP Activity  on 4 September '12

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
