Meteorwrongs Never Fell From Space

Rocks mistakenly identified as meteorites have earned the joking name "meteorwrongs." The term covers terrestrial rocks and human-made objects that people believe or claim came from space. Common impostors include hematite concretions and industrial slag, whose unusual shapes, metal grains, or bubbled surfaces can resemble meteorite features. Some cases require chemical or mineralogical testing before researchers can rule them out, and scientists sometimes call ambiguous examples pseudometeorites.
