Traffic Report  on 15 November '12

Ten objects reported inside ten LD

Ten objects are reported flying within ten lunar distances (LD) of our home world today. Within Earth's Hill sphere, risk-listed intruder 2012 VJ38 is headed out from 1.13 to 2.09 LD, and risk-listed 2012 VS76 enters the sphere, going from 4.86 to 2.94 LD.

Newly discovered intruder 2012 VH77 is currently outbound from 5.35 to 7.85 LD. It is preliminarily calculated with some uncertainty to have flown past Earth at 0.52 LD on November 12th.

Risk-listed 2012 VU76 is inbound from 8.32 to 8.11 LD and newly announced risk-listed 2012 VE77 enters ten LD, moving from 11.11 to 8.14 LD, as does 2012 VN76, coming in from 11.1 to 9.9 LD*.

The other four objects are all outbound: 2012 VC26 from 4.33 to 5.37 LD, 2012 UY68 from 6.81 to 7.11 LD, and 2012 UV136 from 7.26 to 7.86 LD, while 2012 VR76 departs from inside ten LD, traveling from 9.38 to 10.32 LD, and

Approaching Earth next, 2012 VB26 arrives inside ten LD tomorrow and radar target 2010 JK1 arrives on November 22nd.

This report was generated at 1928 (plus a risk listing addition at 1947) UTC with new discoveries 2012 VH77 (MPEC) and 2012 VE77 (MPEC) and follow-up in today's DOU MPEC for 2012 VU76, 2012 VS76, 2012 VR76, and 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.

Impact Risk Monitoring  on 15 November '12

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2359 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
