While most asteroids are made of rock or ice, the incredibly dense Psyche is made mostly of metal, and measures about 140 miles in diameter, making it the size of Massachusetts. The Planetary Science Journal’s new study has found that Psyche may be composed of iron and nickel, which are typically found in the cores of planets. “We’ve seen meteorites that are mostly metal, bu
