I discussed the possibility of terrestrial meteorites in Rubin (2015),
Icarus 257, 221-229. Neglecting the effects of the Earth's atmosphere,
it would take five times as much energy to launch a basaltic rock off
the Earth as it would to launch the same mass rock off Mars. Except
for Black Beauty,
Thirty years ago, my thesis advisor, Don Brownlee, and I talked about
potential terrestrial meteorites and how their "asteroids" might be
identified among the population of near-Earth objects. Unfortunately for me
at the time, we decided that any strong identification would rely on
details of
Albert Jambon classified NWA 5363 which is paired to NWA 5400, both of which
plot on the TFL, leading many to speculate an earth origin.

Most of the meteorites found on Earth come from asteroids, but a few come
from other bodies like Mars and the moon. Now, researchers say they have
discovered a new kind - a rock originally from Earth that went to space
then came
There is also the possibility that there are,orbiting the Sun, hundreds of
rocks from the Chicxulub Impact 65 million yearsago that caused an ecological
catastrophe that killed all the large dinosaurs.This may not one of them, alas,
but the rocks are out there. It would be sure
