These radar images come from Goldstone's 70-meter dish catching 2007 TU24 when it was just over eleven lunar distances (LD) away on January 24th. At 0834 UTC tomorrow it will pass Earth at 1.44 LD, observable in backyard telescopes. JPL describes 2007 TU24 as "somewhat asymmetrical in shape, with a diameter [of] roughly 250 meters." See A/CC's 2007 TU24 links for more info. Credit: NASA/JPL-Caltech.

Impact Risk Monitoring on 28 January '08

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS and JPL at 2354 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of 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.

2008 AF4	NEODyS	1449	2067-2090	9	1.62e-06	-3.49	-3.62	0	NEODyS: "Based on 304 optical observations (of which 3 are rejected as outliers) from 2008/01/10.397 to 2008/01/27.727."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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