Traffic Report  on 3 October '12

One object reported inside ten LD

One asteroid is reported to be within ten lunar distances (LD) of Earth today. 2012 SJ58 is calculated to come its closest to Earth on this passage, reaching 5.9 LD at 0504 UTC (uncertainty: +/- 53 minutes).

Next known to be approaching, 2010 JK1 arrives inside ten LD on November 22nd.

This report was generated at 1607 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.

Impact Risk Monitoring  on 3 October '12

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2346 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.

Notes for Today's Latest Risk Assessments
2012 SG58NEODyS16072060-206012.5e-08-6.50-6.50NEODyS: "Based on 28 optical observations (of which 1 are rejected as outliers) from 2012-09-26.260 to 2012-10-02.497."

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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