Traffic Report  on 29 November '12

Two objects reported inside ten LD

Two visitors are reported to be inside ten lunar distances (LD) from our planet today. 2012 WH1 comes its closest to Earth this time around, reaching 7.62 LD at 0931 UTC, and risk-listed 2012 WR10 is outbound from 8.57 to 9.25 LD. Headed our way next, 2009 BS5 arrives inside ten LD on December 7th.

This report was generated at 1627 UTC with follow-up in today's DOU MPEC for 2012 WH1.


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.
