Traffic Report  on 1 January '13

One object reported inside ten LD

There is one asteroid reported to be within ten lunar distances (LD) of our planet today. Radar target 2012 XM55 is outbound from 5.97 to 6.52 LD. Next known to be on approach is intruder 2012 DA14, a risk-listed radar target that arrives inside ten LD on February 8th.

This report was generated at 1621 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.
