Impact Risk Monitoring on 29 June '09
| 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 MN8 | JPL Sentry | 1601 | 2065-2108 | 3 | 8.0e-09 | -7.14 | -7.37 | 0 | JPL: "Analysis based on 9 observations spanning .89031 days (2009-Jun-28.66337 to 2009-Jun-29.55368)." Diameter approximately 0.093 km. from mean, weighted H=22.8. |
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
