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.
0000NNN000 Object	Risk Monitor	When Noted UTC	0000T0000 Year Range	VI #	000NN00 Prob Cum	T0000 PS Cum	T0000 PS Max	T S	Notes for Today's Latest Risk Assessments

2009 KK	JPL Sentry	1432	2022	1	9.6e-05	-1.17	-1.17	1	JPL: "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.
2009 KK	NEODyS	1324	2022	1	9.55e-05	-1.17	-1.17	1	NEODyS: "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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
