NWA stands for Northwest Africa, where this meteorite was found in 2015. The number 11115 means that this is the 11,115th meteorite found in the region. In 2016 Field Museum scientist, together with an international team of colleagues, confirmed that this is a piece of Mars’s crust knocked from the surface if that planet by an asteroid.
It may look boring on the outside but this meteorite is filled with clues about a world that—depending on the positions of our orbits—can be as “close” as 34 million miles away, or as far as 249 million miles away.
