Traffic Report  on 24 February '13

Two objects reported inside ten LD

There are two visitors reported to be inside a radius of ten lunar distances (LD) from Earth today. 2013 DS9 comes its closest to Earth this time around, reaching 8.66 LD at 2145 UTC, and radar target 2013 BS45 exits from ten LD, passing from 9.53 to 10.14 LD.

Headed our way next, risk-listed 2007 EO88 arrives inside ten LD on March 15th.

This report was generated at 1656 UTC with follow-up in today's DOU MPEC for departed 2013 CZ87 and 2013 CE82 and distant 68216 2001 CV26.



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.
