NASA Rules Out Apophis Asteroid Collision In 2036
redOrbit Staff & Wire Reports – Your Universe Online
There is a less than one-in-a-million chance that a massive asteroid, approximately as wide as three American football fields, will collide with Earth in 2036, NASA officials confirmed on Wednesday.
According to MSNBC.com’s Alan Boyle, the “all-clear” was sounded by the US space agency after asteroid Apophis came within nine million miles of our planet.
In fact, officials with NASA’s California-based Jet Propulsion Laboratory told Boyle the space rock would probably miss Earth by 36 million miles, and would absolutely pass no closer than 14 million miles away.
“The scientists used updated information obtained by NASA-supported telescopes in 2011 and 2012, as well as new data from the time leading up to Apophis’ distant Earth flyby yesterday (Jan. 9),” officials from the organization explained in a statement.
“Discovered in 2004, the asteroid… gathered the immediate attention of space scientists and the media when initial calculations of its orbit indicated a 2.7 percent possibility of an Earth impact during a close flyby in 2029,” they added. “Data discovered during a search of old astronomical images provided the additional information required to rule out the 2029 impact scenario, but a remote possibility of one in 2036 remained – until yesterday.”
Using the Goldstone Solar System Radar located in the Mojave Desert, JPL scientists recorded single-pixel observations of Apophis, which is what allowed them to officially rule out the threat of impact, according to Discovery News.
However, Dan Vergano of USA Today notes the asteroid will approach closely in 2029, when it is less than 20,000 miles away, or 10 times closer to the Earth than the moon.
While NASA officials called that fly-by “one for the record books,” Don Yeomans, manager of the agency’s Near-Earth Object Program Office at JPL, said “a closer approach by a lesser-known asteroid” was going to take place “much sooner” than that. In fact, he said that, “in the middle of next month… a 40-meter-sized asteroid, 2012 DA14, flies safely past Earth’s surface at about 17,200 miles.”
“With new telescopes coming online, the upgrade of existing telescopes and the continued refinement of our orbital determination process, there’s never a dull moment working on near-Earth objects,” he added.

17, 000 miles is extremely close. Any minute error can change this to impact. Very suspicious and error backing that Russian scientist disagree and say it will be on course for impact. We need proof. Proof from Russia US is wrong. Perhaps on this site. Maybe an email to this scientist.
Why is everyone worrying about Apophis? It’s about 330 metres long and 20 odd years away!
What about the one that is coming in September that is 3 KM long and travelling in the opposite head on impact direction – Unlike Apophis!

What’s really unusual is that the calculated orbit is inclined 155° to the plane of the Earth’s orbit. That means that as it orbits the Sun, it actually travels backwards compared to the planets. It is only the 20th asteroid known in a retrograde orbit, a very rare group. None of the others comes as close to the Earth.
The retrograde orbit of this asteroid will greatly increase the ‘speed at impact’ of this object, colliding with the Earth
The retrograde orbit of this asteroid will greatly increase the ‘speed at impact’ of this object and its potential for major damage. This is because both the Earth and HC82 will be travelling towards each other at high speed, like two trains heading towards each other on the same track.
And remember the asteroid that killed off the dinosaurs was 10 km wide and I don’t think it was travelling on a retrograde orbit. Oh and the asteroid belt? That used to be a planet!
