Traffic Report  on 15 November '13

Two objects reported inside ten LD

There are two objects reported passing within ten lunar distances (LD) of our planet today. Radar target 2001 AV43 enters Earth's Hill sphere, moving from 4.29 to 3.76 LD and 2011 JY1 is outbound from 7.06 to 8.32 LD.

Up next, 2013 VK13 arrives inside ten LD on November 17th and radar target 2013 NJ arrives on November 19th.

This report was generated at 0236 UTC, noting astrometry posted late yesterday in a DOU MPEC (the first since November 11th) for 2013 VK13 and departed objects 2013 VP11, 2013 VO11, 2013 VK11, intruder 2013 VJ11, and risk-listed 2013 VM5.



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. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 15 November '13

The MPC's NEO Confirmation Page has 15 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had fifteen objects listed. Of these, five were "one nighters." The Tracking News counted a total of eighteen listings on the NEOCP on this day.

Impact Risk Monitoring  on 15 November '13

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
