Traffic Report  on 2 October '12

One object reported inside ten LD

There is one object reported passing within ten lunar distances (LD) of Earth today. 2012 SJ58 is calculated with some uncertainty to be inbound from 6.6 to 5.9 LD. Headed our way next, 2010 JK1 arrives inside ten LD on November 22nd.

This report was generated at 2310 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.
