Traffic Report  on 9 November '13

Three objects reported inside ten LD

Three asteroids are reported moving within ten lunar distances (LD) of Earth today. Radar target 2001 AV43 is inbound from 8.35 to 7.63 LD while 2013 UE1 is outbound from 7.70 to 8.45 LD and 2013 VH2 from 8.90 to 9.61 LD.

Coming into the neighborhood next, 2011 JY1 arrives inside ten LD on November 11th and radar target 2013 NJ arrives on November 19th.

This report was generated at 1644 UTC with first follow-up in today's DOU MPEC for departed objects 2013 VL5, 2013 VL, and risk-listed 2013 VM5, astrometry for 2013 UE1 and departed object 2013 UQ5, and observation of radar target 2013 SU24 from October 1st and of distant radar target 152664 1998 FW4 during September.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. "Distant" is used to describe objects that have come within ten LD since this reporting began (2007) but are not so close during the reported passage or apparition. 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.

Impact Risk Monitoring  on 9 November '13

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2358 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
