This one could be a game ender for Earth....Hey... It could happen.
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.
