On December 24, 2004, 370 m (1,210 ft) asteroid 99942 Apophis was assigned a 4 on the Torino scale, the highest rating given to date, for an impact in April 2029. [19] As observations were collected over the next three days, the calculated chance of impact first increased to as high as 2.7%, [ 20 ] then fell back to zero. [ 21 ]
