This montage by Emily Lakdawalla, in its large full version with or without text, shows the image and relative size of every asteroid and comet visited by space missions to date -- eight solitary asteroids, one asteroid with a satellite, and four comet nuclei. The big rock is the just visited Main Belter, 21 Lutetia, and the smallest object, NEO 25143 Itokawa, doesn't show in this thumbnail. Credit: Numerous NASA and ESA space missions and imaging teams.

Impact Risk Monitoring on 19 July '10
| 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 |
| 2010 NB2 | NEODyS | 1215 | 2023 | 1 | 8.08e-11 | -7.14 | -7.14 | 0 | NEODyS: "Based on 25 optical observations (of which 1 are rejected as outliers) from 2010/07/10.316 to 2010/07/17.985." |
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
