Yesterday Apophis passed by our planet at a distance of about 9 million miles. The Goldstone tracking station in California has been tracking this asteroid for about the last week now using radar, and those observations have allowed astronomers to refine the orbital determination and rule out any possibility of an impact in 2036. It will still make a very close pass in 2029, but it turns out that it will be farther from us in 2036 than it was yesterday.



Based on revised orbit calculations, he says Apophis will then come no closer than about 14 million miles — and more likely miss us by something closer to 35 million miles. Moreover, the radar data have improved the asteroid's positional uncertainty so much that dynamicists can now accurately predict its trajectory decades into the future.

JPL's NEO threat list website still shows a possibility for 2036 (though it's much lower than it used to be now at about a 1 in 7 million chance), but the data they're using for the website only takes into account observations up to December 29th as of the last time I checked it a few minutes ago.

Once the new observations are incorporated into the website's data (Goldstone is scheduled to continue observing the asteroid from Jan 3-17th echo.jpl.nasa.gov... ), that possibility will vanish.

Maaaannn,first they took Elenin away,then Nibiru,now Apophis.Where is this madness going to stop?

Thanks for the thorough update, ngchunter!

Just some other related information that I thought would be useful for anyone else interested in this subject.


PASADENA, Calif. - Scientists using the Herschel Space Observatory made new observations of asteroid Apophis as it approached Earth this past weekend. The data show the asteroid to be bigger than first estimated, and less reflective. Discovered in 2004, Apophis was initially thought to have a 2.7 percent chance of impacting Earth in 2029. Additional observations of the asteroid ruled out any possibility of an impact in 2029. However, Apophis is expected to make a record-setting -- but harmless -- close approach to Earth on April 13, 2029, when it comes no closer than 18,300 miles (29,450 kilometers) above Earth's surface. The asteroid will make another approach to Earth in 2036. Data collected by telescopes during today's close approach are expected to refine the asteroid's orbit to the point where an impact in 2036 can be ruled out.

The Herschel Observatory is a European Space Agency mission in which NASA plays an important role.
