The meteorite would have started its journey from the Jupiter-Mars asteroids belt, leaving it at some point and begun floating freely in space. Eventually, this mass intersected with the Earth's own orbit where its surface was flash-heated to 2,800 degrees Fahrenheit on entry, then rapidly cooled in the frigid temperatures of Earth's upper atmosphere, before slowing to approximately 200 miles per hour on its final descent. This fall would have lit the Spanish sky up before hurtling down to its site of discovery.
