Impact Risk Monitoring  on 3 June '09

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. Beginning Jan. 22nd, both are also posting impact solutions beyond 100 years for a few objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Notes for Today's Latest Risk Assessments
2009 KKJPL Sentry1432202219.6e-05-1.17-1.171JPL: "Analysis based on 92 observations spanning 15.990 days (2009-May-17.25987 to 2009-Jun-02.24985)." Diameter approximately 0.270 km. from mean, weighted H=20.5.
NEODyS1324202219.55e-05-1.17-1.171NEODyS: "Based on 92 optical observations (of which 0 are rejected as outliers) from 2009/05/17.261 to 2009/06/02.251. NOTE: The Virtual Impactor in 2022/05/29.761 ... is rated as Torino Scale 1."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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