Impact Risk Monitoring on 25 August '10
Notes for Today's Latest Risk Assessments
|2010 PR66||JPL Sentry||1442||2098-2107||2||1.8e-07||-4.22||-4.22||0||JPL: "Analysis based on 100 observations spanning 8.8982 days (2010-Aug-15.2648 to 2010-Aug-24.162972)." Diameter approximately 0.450 km. from mean, weighted H=19.4.|
|2010 PS65||JPL Sentry||1442||2102||1||2.2e-06||-5.79||-5.79||0||JPL: "Analysis based on 35 observations spanning 10.022 days (2010-Aug-13.29423 to 2010-Aug-23.31639)." Diameter approximately 0.041 km. from mean, weighted H=24.6.|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
