Traffic Report  on 10 November '12

Ten objects reported inside ten LD

There are ten asteroids reported to be inside ten lunar distances (LD) of our planet today. Within Earth's Hill sphere, 2012 VQ6 comes its closest to Earth this time around, reaching 1.77 LD at 1135 UT, and its closest to the Moon -- 2.02 LD at 1853 UT, and 2012 VC26 moves inward from 3.26 to 2.56 LD.

More distantly, 2012 UV136 comes its closest to Earth on this passages, reaching 5.79 LD at 0749 UT, and risk-listed 2012 UY68 is inbound from 8.27 to 7.63 LD. All the others are outbound. 2012 VB5 passes from 5.08 to 7.46 LD, 2012 VA26 from 5.15 to 5.88 LD, 2012 UX136 from 6.68 to 7.80 LD, and 2012 UL171 from 9.5 to 10.0 LD*, while 2012 VE26 exits from ten LD, flying from 8.47 to 12.67 LD, as does 2012 VD5, which travels from 9.23 to 11.76 LD.

Next up, 2012 VB26 arrives inside ten LD on November 16th and radar target 2010 JK1 arrives on November 22nd.

This report was generated at 1621 UTC with follow-up in today's DOU MPEC for departed 2012 UK171.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Earth's Hill sphere (of gravitational influence) is estimated to extend out to around 3.89 LD. Object distances are interpreted by A/CC from JPL Horizons data. "LD*" indicates some passage uncertainty. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 10 November '12

The MPC's NEO Confirmation Page has 25 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 25 objects listed. Of these, eleven were "one nighters." So far The Tracking News has counted a total of 40 listings on the NEOCP today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
