Impact Risk Monitoring on 27 June '10
Notes for Today's Latest Risk Assessments
|2010 MF1||JPL Sentry||1447||R E M O V E D||JPL: Risk listing removed at 0849 UTC.|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
