Traffic Report  on 11 July '12

One object reported inside ten LD

One object is reported traveling within ten lunar distances (LD) of Earth today. Radar target 2012 MY2 is outbound from 9.13 to 9.93 LD. No other objects are known to come within ten LD until November.

This report was generated at 1356 UTC with follow-up in today's DOU MPEC for departed 1999 XL136.


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 11 July '12

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 1917 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 MA7JPL Sentry1354R E M O V E DJPL: Risk listing removed at 0850 UTC.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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