2006 imagery from the Hubble Space Telescope of 136199 Eris (2003 UB313) seemed to reinforce earlier evidence that this distant object is larger than Pluto, as reported in 2007. That has been challenged now by an Eris stellar occultation observed from Chile on November 6th which indicates that the more massive Eris has a diameter at or just under Pluto's.

NEOCP Activity on 9 November '10
The MPC's NEO Confirmation Page has 2 listings: 2 new
When last checked at 2311 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two new listings. Both of these were "one nighters." So far The Tracking News has counted a total of sixteen listings on the NEOCP at some point today.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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