The asteroid Psyche may have once had vents that spewed molten metal — but only if it is chemically similar to rare, metal-rich meteorites, a new study suggests. The study, which was published online July 31 in the Journal of Geophysical Research: Planets, could explain why the space rock has an unusual metallic cloak.
Potato-shaped asteroid Psyche, a member of the main asteroid belt between Mars and Jupiter, is unique in being super-shiny. Radar measurements indicate that, on average, its surface reflects nearly a third of the sunlight shining on it, making it at least twice as reflective as most asteroids.
