Traffic Report  on 1 December '12

Two objects reported inside ten LD

Two objects are reported to be within ten lunar distances (LD) of our planet today. 2012 WH1 is outbound from 8.16 to 8.97 LD and risk-listed 2012 WR10 departs from inside ten LD, traveling from 9.93 to 10.62 LD.

The next known visitor, 2009 BS5, arrives inside ten LD on December 7th.

This report was generated at 1826 UTC.


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.
