Traffic Report  on 5 October '12

One object reported inside ten LD

There is one object reported flying inside ten lunar distances (LD) of Earth today. 2012 SJ58 is outbound from 7.29 to 8.89 LD. Headed our way next, 2010 JK1 arrives inside ten LD on November 22nd.

This report was generated at 1834 UTC with today's DOU MPEC reporting the recoveries of, and first follow-up for 2012 SJ58 and departed 2012 SR56.


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.
