Traffic Report  on 22 July '13

No objects reported inside ten LD

No asteroids are reported traveling within ten lunar distances (LD) of our planet today. Headed our way next, 2006 BL8 may arrive inside ten LD on July 24th (uncertainty +/- two days) and 2003 DZ15 arrives on July 28th.

This report was generated at 1401 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.
