Asteroid Apophis, once considered a potential threat to Earth, is now ruled out as a hazard for at least a century. NASA used radar observations and precise orbit analysis to confirm the safe distance of the 1,100-foot-wide near-Earth object.
Apophis is a near-Earth asteroid that was once considered a potential threat to Earth, but no longer. NASA scientists used radar observations and precise orbit analysis to rule out any impact risk in 2068 and beyond.
Asteroid 99942 Apophis, which was once considered a potential threat to Earth, is now ruled out as a hazard for at least a century. Radar observations and orbit analysis by NASA and NSF have improved the accuracy of its trajectory and orbit.
99942 Apophis is a near-Earth asteroid that was once considered a potential threat to Earth in 2029 and 2036. It is now known that it will not hit Earth in 2036, but it may come close in 2051 and 2068 due to the Yarkovsky effect.
But a potential 2068 collision still loomed. First detected in 2004, Apophis is now officially off NASA's asteroid "risk list." "A 2068 impact is not in the realm of possibility anymore, and our calculations don't show any impact risk for at least the next 100 years," Davide Farnocchia of NASA's Center for Near-Earth Object ...
Radar measurements rule out any chance of a collision with Apophis over the next 100 years. The asteroid will pass close to Earth in 2029 and 2068, offering opportunities for observation and imaging.
NASA announced that the potentially menacing asteroid Apophis won't hit the Earth in 2068 after all. The Empire-State-Building-sized space rock will come close to Earth in 2029 and 2036, but not pose any threat for at least a century.
"A 2068 impact is not in the realm of possibility any more, and our calculations don't show any impact risk for at least the next 100 years," Davide Farnocchia, a scientist who studies near-Earth ...
A new study shows that the sun's heat can change the orbit of the near-Earth asteroid Apophis, which could pose a threat to Earth in 2068. Scientists need to track the asteroid carefully and observe its close approach in 2029 to rule out or confirm the impact scenario.
Asteroid Apophis, which was once thought to pose a slight risk of hitting Earth in 2068, is now ruled out by radar observations and precise orbit analysis. The near-Earth object will make a distant flyby of Earth on March 5 and will be visible on April 13, 2029.
