Sky view on March 24th 
at 0000 UTC. A/CC illustration.

There is today one asteroid, the unobserved 2003 FY6, predicted to be within ten lunar distances (LD) of Earth. No others are known to be approaching until early July, but you can expect there to be many, hidden by the bright Moon, or too dim or fast to be caught, or passing outside the areas surveyed most. A/CC's new Timeline page for Earth's Busy Neighborhood shows an average of eighteen objects per month were known to have passed within ten LD since October.

Impact Risk Monitoring  on 24 March '08

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2353 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.
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Notes for Today's Latest Risk Assessments
2007 FY20NEODyS14132085-208833.24e-07-6.65-6.810NEODyS: "Based on 60 optical observations (of which 0 are rejected as outliers) from 2007/03/26.203 to 2007/04/01.870, and also on one radar data point on 2007/03/31."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
