Thanks, those are pretty cool.

These random chunks of debris are probably the source for all regional and global extinction events, imho. Rather than trying to attribute the large impacts (K-T, P-T, Manicougan, Reis, etc) to some nice orderly cyclical process involving crap from the so-far fictional Oort Cloud, the likelihood is that spirograph-like rendezvous as well as gravitational come-hithers by the Earth, maybe our Moon, and by the other inner planets, plus Jupiter, are the source of the impactors. Junk floating quietly along in orbits very similar to Earth’s can stay put for long periods, see-sawing around a bit, until the day they get a little too much stimulation. Then here they come.

If you go to http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2002%20VE68;orb=1;cov=1;log=0;cad=0#elem you can visualize its orbit. The Earth will “cross” its orbit on October 25 and November 25 this year. Its orbit currently passes well above (north) and below (south) of earth’s orbit. Unless (rather, until) perturbed, it should not be a threat. If you click the Horizons homepage above you get more precise ephemerides, but only for the period 1600-2200 AD.
Merry Christmas to you too!
Be afraid...

The quasi-satellite has to ring the bell at Notre Dame every hour, so I’m not that worried.
Nah. It says, “stalked by a quasi-satellite,” not a “crazy sado-lite.”

How about not just a "close encounter" but one different from those it'd been experiencing for the last 100,000 years ~ when Earth tilted a little bit differently than it does now due to its quite extensive ice load.
On that latest close counter Earth didn't have all that ice and the mass of water was distributed far differently than those earlier periods.
Also, how close was the encounter? Is it possible this chunk came close enough to provide just enough tug to pull a Mediterranean bole over the Bosporus and cut a channel sufficient to maintain Black Sea contact with the Aegean?
And here's a big chunk of rock cruising through ~ kind of like to know if that sucker was VISIBLE too ~ and if VISIBLE did it have a fiery trail.
A really gigantic bolide would draw attention to itself ~ and get mentioned by Sumerians!
This be a night time visit as well, with the object approaching Earth slowly ~ finally passing by Earth along the Mediterranean Basin, and building up a bole of some serious note ~ maybe a few hundred feet ~ or maybe it was close enough to draw up a soliton and that could go up to a thousand feet. Whatever it did you could compute the energy taken to raise up enough water to crash across the Bosporus as well as to change this critter's orbit.
In later passings it'd be essentially invisible although remembered for a really, really long time.
You did know that the Sumerians report that God created Gilgamesh first, then Inkydu later, but he was an "hairy" man who ran wild with the animals, etc. An Earthgrazer, if it cruised through the atmosphere, would seem to have "hair".
Cruithne?
What kind of sci-fi geek name is that? It’s like Cthulu only different. When you let the geeks do the naming, you inevitably get Klingon sounding crap like “Cruithne”.
On the other hand, they’re the ones who spend hours and days and months searching for these things, so there is justice in letting them name them.
So, I guess Cruithne it is.
The Sumerians were busy inventing writing 5,000 years ago, but they were by that time already well practiced at ACCOUNTING.
If there are anomalies in the tables, the fact the information came from 5000 years go rather than 3700 years ago may be a clue to determining whether they were watching Venus or a chunk of rock.
if this hunk is Inkydu, we're really in the grove, eh!
