Missing something? Here are 99942 Apophis (2004 MN4) and 144898 2004 VD17. Check the archives for others.

Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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