(C) Steven M. Tilley

Note at time of upload 2015 PU228 is listed on the "Sentry Risk Table" and the "NEODyS CLOMON2 risk page" as Torino Scale 1.

HOWEVER this is NOT a prediction of an impact but rather a statement there is insufficient observational data rule out an impact on 2081-01-15.40 With additional observations this asteroid will likely be re-assignment to Torino Scale 0.

Torino Scale

at the time of upload the chance the asteroid will MISS the Earth is 99.9928%
