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.
A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7 percent chance of striking Earth in 2029. Further observations ruled out an impact. "City killer ...
In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a ...
A huge asteroid will fly by Earth in April 2029. It won't be close enough to hit us, but it will be close enough to study, so scientists are getting ready. ... astronomers were startled to realize ...
Three years later, in 2012, the 40 meter diameter asteroid 367943 Duende was discovered and successfully predicted to be on close but non-colliding approach to Earth again just 11 months later. This was a landmark prediction as the object was only 20 m × 40 m , and it was closely monitored as a result.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
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. ... least 100 years, astronomers say. No, not ...
The asteroid came closest to Earth on Christmas Day — passing within roughly 500,000 miles (800,000 kilometers) of Earth, about twice the distance of the moon. It was discovered two days later. Chodas said scientists are poring over sky surveys from 2016, when predictions show the asteroid also ventured close.
