Scientists think that metallic asteroids began their lives as blobs of molten iron, floating in space.
Of the nearly 800,000 known asteroids in our solar system, a significant proportion are made of metal. Scientists think these objects began their lives as blobs of molten iron, suspended in space.
“We predict iron volcanism to have occurred on metallic asteroids as they cooled and discuss the implications of this process for both the evolution and the modern appearance of these bodies,” the authors wrote. The researchers suggest that the volcanoes would behave differently, depending on the specific characteristics of the asteroid in question.
