The cumulative impact probability was estimated to be around 0.004%, a risk lower than that of asteroid 2004 VD 17, which once again became (temporarily) the greatest-risk object. A 2053 approach to Earth still posed a minor risk of impact, and Apophis was still rated at level one on the Torino scale for this orbit. 2004-12-28: 12:23 GMT
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 ]
Currently, no impacts are predicted (the single highest probability impact currently listed is ~7 m asteroid 2010 RF 12, which is due to pass Earth in September 2095 with only a 10% predicted chance of impacting; its size is also small enough that any damage from an impact would be minimal).

The asteroid 2024 YR4 is now rated at Level 3 out of 10 on the Torino Impact Hazard Scale, ... A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7 ...
Based on projections, the asteroid has little more than a 1% chance of impacting Earth on Dec. 22, 2032. For context, 2024 YR4 rates at a 3 on the Torino Impact Hazard Scale. The scale, which ...
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
There are 1888 near-Earth asteroids listed in the risk table and 41,848 virtual impact dates, so for each asteroid in the risk table, there is an average of about 22 virtual impact dates. Only about 21 objects in the table are large enough, with a diameter greater than about 140 meters, to be considered potentially hazardous objects .
The probability of impact crossed 1% in late January and reached 1.9% Wednesday. The latest calculations Friday show the odds have increased a little more to 2.3%. ... the scale suggests: "A close ...
