The NEO 2016 WJ1 Has Been Removed from the Sentry Risk Table--Neodys Risk Table List 3 Possible Impacts 2106-2115.

On December 2, 2016 at 21:33(UTC) NASA JPL removed the NEO 2016 WJ1 from the Sentry Risk Table. Whenever an object is posted to one the risk lists (especially if it has a Torino Scale 1 or greater) and it is observable, observers will take a particular interest in it. In the case of 2016 WJ1 many follow-up observations where made and there was a search in archives for precovery observations. From November 24, 2016 to December 2, 2016 through the work of many observers from around the world the number of optical observations went from 68 to 240 and the data-arc span went from 5 days to 4899 days (13.41 yr). This allowed for the calculation of orbital elements with lower uncertainty and NASA JPL rule out potential impacts well into the future. Notice: Neodys risk table list 3 possible impacts 2106-2115.

NOTE this is NOT a prediction of an impact but rather a statement there is insufficient observational data rule out an impact -- for information read Understanding Risk Pages by Jon Giorgini

Torino Scale(NEODyS CLOMON2): 0

The likelihood of a collision is zero, or is so low as to be effectively zero. Also applies to small objects such as meteors and bodies that burn up in the atmosphere as well as infrequent meteorite falls that rarely cause damage."
