Impact Risk Monitoring on 19 March '20

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS at 2231 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.
The time horizon for JPL and NEODyS listings is 100 years, and both post impact solutions beyond that for some special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.
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

2020 FE2	JPL Sentry	2231	2076-2079	2	6.457e-07	-6.66	-6.85	0	JPL: Computed at 14:58 today Pacific time based on 24 observations spanning 1.6253 days (2020-Mar-18.17316 to 2020-Mar-19.79844). Diameter approximately 0.026 km. from weighted mean H=25.58.

2020 FD2	JPL Sentry	1632	2100-2100	1	4.466e-10	-9.39	-9.39	0	JPL: Computed at 07:18 today Pacific time based on 20 observations spanning 1.4311 days (2020-Mar-17.64034 to 2020-Mar-19.07141). Diameter approximately 0.025 km. from weighted mean H=25.65.
2020 FD2	NEODyS	1632	2087-2104	3	3.97e-10	-9.37	-9.64	0	NEODyS: "Based on 20 optical observations (of which 0 are rejected as outliers) from 2020-03-17.641 to 2020-03-19.072."

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale (next 100 years)

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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