Impact Risk Monitoring on 25 October '10
Notes for Today's Latest Risk Assessments
|2010 TU149||JPL Sentry||1728||2077||1||4.4e-08||-4.90||-4.90||0||JPL: "Analysis based on 62 observations spanning 8.9107 days (2010-Oct-13.37823 to 2010-Oct-22.288923)." Diameter approximately 0.270 km. from mean, weighted H=20.5.|
|NEODyS||1728||R E M O V E D||-|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
