"Sentry follows other attempts to deal with the publication of asteroid risk data. A color-coded disaster yardstick called the Torino Scale, developed in 1999 and designed in part to inform the media and the public, has gone largely unused. On the Torino Scale, a zero or one represent remote risk, and a 10 means it's time to sell the farm."
************************
I say again, it's time to scrap the Torino scale's well intentioned but failed attempt at communicating with the public and leverage off the new homeland defense threat scale and use the same colors for asteroid threat categorization.
