Hi Michael,

Thanks for the opinion... Could you share some of the research? Papers,
articles, maps, photos, classifications etc...

Though I appreciate and respect it, I just have a hard time grasping or
believing a coincidence in this circumstance. Statistically it seems
very possible they are related and from the same parent body. In fact
the probability of them NOT being related seems remote as it doesn't
make sense not to consider the likelihood of a pairing relationship. Or
am I just trying to talk myself into it? ;)

Has anyone looked at Google Earth and zoomed out to see how small a spot
that actually is? That's like shooting a speeding bullet our of the air
with another. The Earth is rotating ~365 times per year, x 11 years
that's 4015 rotations of the earth and 11 complete orbits around the
Sun. Two small rocks of the same exact type floated around the solar
system for millions/billions of years, and crash land within 1.4 miles
of each other only 11 years apart and they are not related?

So basically it's a coincidence? ;)

Regards,
Eric
