NASA Rules Out Possibility of Impacts in 2036 and 2068 for Asteroid Apophis

NASA Rules Out Possibility of Impacts in 2036 and 2068 for Asteroid Apophis

Apophis was discovered on June 19, 2004, by astronomers at the Kitt Peak National Observatory in Tucson, Arizona. Estimated to be about 1,100 feet (340 meters) across, Apophis quickly gained notoriety as an asteroid that could pose a serious threat to Earth, when astronomers predicted that it would come uncomfortably close in 2029. Thanks to additional observations of the Near-Earth Object (NEO), the risk of an impact in 2029 was later ruled out, as was the potential impact risk posed by another close approach in 2036. Until this month, however, a small chance of impact in 2068 still remained. But when Apophis made a distant flyby of Earth around March 5, 2021, astronomers took the opportunity to use powerful radar observations to refine the estimate of its orbit around the Sun with extreme precision, enabling them to confidently rule out any impact risk in 2068. Now, there is no risk of Apophis impacting our planet for at least a century.

NASA ruled out the impacts?! Gosh darn it, and I was counting on it too!

What would be the extent of the damage if it were to strike a major city or if it impacts the ocean, what extent would the tsunami be?

As far as damage to cities is concerned, your guess is as good as mine.

But here is an interesting simulation of an impact by Apophis:
