A/CC's Consolidated Risk Tables

Earth Impact Risk Ratings Posted in the Last 31 Days

Compiled at 0501 UTC on 7 April 2020

[ The Tracking News | ephemerides | cleared ]

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 NASA/JPL Sentry and NEODyS CLOMON2.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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