Predicting Apophis’ Earth Encounters in 2029 and 2036
http://neo.jpl.nasa.gov/apophis/

The analysis of Apophis previews situations likely to be encountered with NEAs yet to be discovered: a close approach that is not dangerous (like Apophis in 2029) nonetheless close enough to obscure the proximity and the danger of a later approach (like Apophis in 2036) by amplifying trajectory prediction uncertainties caused by difficult-to-observe physical characteristics interacting with solar radiation as well as other factors...

The future for Apophis on Friday, April 13 of 2029 includes an approach to Earth no closer than 29,470 km (18,300 miles, or 5.6 Earth radii from the center, or 4.6 Earth-radii from the surface) over the mid-Atlantic, appearing to the naked eye as a moderately bright point of light moving rapidly across the sky. Depending on its mechanical nature, it could experience shape or spin-state alteration due to tidal forces caused by Earth’s gravity field.

This is within the distance of Earth’s geosynchronous satellites. However, because Apophis will pass interior to the positions of these satellites at closest approach, in a plane inclined at 40 degrees to the Earth’s equator and passing outside the equatorial geosynchronous zone when crossing the equatorial plane, it does not threaten the satellites in that heavily populated region.

Using criteria developed in this research, new measurements possible in 2013 (if not 2011) will likely confirm that in 2036 Apophis will quietly pass more than 49 million km (30.5 million miles; 0.32 AU) from Earth on Easter Sunday of that year (April 13).

Big enough to spur catastrophe junkies to predict some crazy impending disaster.

i wunt mind a NEO that was a bit more than a NEO that just kinda sorta scraped a bit of asia off the planet

An object about 100 meters across, impacting in Tehran, would pretty much erase a lot of future problems.

It’s enough to bring on some more wild-eyed talk about various prophetic outcomes, 12th planet, and of course, massive conspiracies by NGO/NWO/Bilderbergers to keep us all in the dark. ;’)

That 2029 pass should be quite an Eiffel, only 18,000 miles up, 1000 feet across, hope we’re on the correct side, and also hope it happens at night so it’ll be easy to spot.

Wait... Has BPEarthwatch heard about this?

This'll give him years of 'You're all gonna die' material... ;-)

Yah, O'Neill and SG-1 must've killed off Apophis 6 or 8 times. Should be no sweat for them, right?

;^)

Apophis was an Egyptian snake god.

Obama wears a snake ring.

Coincidence?

I think not.
