"JPL has updated its 2004 MN4 risk assessment, dropping its Torino Scale rating to zero ("no likely consequences"), and completely eliminating all impact solutions before the year 2037. Overall impact probability is put at one in 55,556. This assessment is based on all reported observations except those in the latest MPEC, 2004-Y71. "
