99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
The asteroid Toutatis is listed as a potentially hazardous near-Earth asteroid, yet poses no immediate threat to Earth.(Radar image taken by GDSCC in 1996.)A potentially hazardous object (PHO) is a near-Earth object – either an asteroid or a comet – with an orbit that can make close approaches to the Earth and which is large enough to cause significant regional damage in the event of ...
The only objects on the Torino scale that have ever ranked higher are asteroids 99942 Apophis, which had a rating of 4 for four days in late 2004, the highest recorded rating; (144898) 2004 VD 17, with a historical rating of 2 from February to May 2006; and 2024 YR 4, with a rating of 3 from January 27, 2025 to February 20, 2025.
At the highest threat, the asteroid only had about a 3% chance of hitting Earth, which was the highest impact probability NASA has ever recorded for an object of this size.
Update: The odds of asteroid 2024 YR4 striking Earth in 2032 have fallen to 1.5%, NASA announced Wednesday. Read the latest.. The risk that an increasingly ominous asteroid dubbed 2024 YR4 will ...
A recently discovered asteroid, named 2024 YR4, is now the riskiest asteroid ever detected. On Tuesday, NASA calculated that the space rock had a 3.1% chance of hitting Earth in 2032, ...
As smaller asteroids are more numerous, ever more close approaches are detected within a given distance. In 2014, scientists estimated that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than the Moon every year, but only a fraction of these are actually detected.
