There could be pieces of iron from Earth's core floating around the solar
system, left over from the collision that created the Moon. Since we have
no direct chemical analyses of Earth core material, when an iron meteorite
falls, how would we know whether it was originally Earth material or not?
I am really surprised that a press release was issued on work that has not
even been submitted for peer-reviewed publication. There seems to be no age
data, no bulk chemical data, and no shock data. The authors seem to claim
it was launched off Earth just 10,000 years ago, but I don't know where

A dark reddish-brown stone, picked up from the Sahara desert in Morocco a
few years ago, appears to be an Earth rock that was flung into space where
it stayed for thousands of years before returning home ? surprisingly intact.
