Traffic Report  on 14 September '12

One object reported inside ten LD

There is one asteroid reported moving inside ten lunar distances (LD) of our planet today. Radar target 2012 QG42 comes its closest to Earth this time around, reaching 7.43 LD at 0513 UTC.

Up next, 2010 JK1 arrives inside ten LD on November 22nd.

This report was generated at 1605 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.
