Traffic Report  on 28 August '12

Two objects reported inside ten LD

There are two asteroids reported passing inside ten lunar distances (LD) of our planet today. 2012 QH14 is outbound from 6.86 to 9.04 LD, and 2012 QZ16 is inbound from 9.95 to 8.10 LD.

Coming our way next, newly announced 2012 QG42 arrives inside ten LD on September 11th.

This report was updated at 2351 UTC with new discovery 2012 QG42 (MPEC) and, earlier, follow-up in today's DOU MPEC for 2012 QV17. Today's first traffic report was generated at 1530 UTC.


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.

NEOCP Activity  on 28 August '12

Impact Risk Monitoring  on 28 August '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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
