The article says, "Rather, the meteorite has "been sitting out there, past Mars, untouched, since before any of the planets were created," Shaun Fowler, a microscopist at Loughborough University, said in a statement, "meaning we have the rare opportunity to examine a piece of our primordial past."

Consider that objects near Mars or just past Mars in the heliocentric solar system, in 1 billion year time period could complete some 530 million revolutions around the Sun. It would be interesting to report the cosmic ray exposure age of this meteorite too and compare with calculated revolutions around the Sun with the radiometric age accepted.
