Missing something? Check the archives for objects not under active observation or recent analysis.

Notes: The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both risk monitors also post a few special objects with impact solutions beyond 100 years. For the latest official risk assessments, and for explanations of terminology and methodology, see the JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

For a list of risk-rated objects currently under observation, see our ephemerides page.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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