Psyche: Why are scientists so interested in this $10,000-quadrillion asteroid?

A new study has found that an asteroid in our solar system, Asteroid 16 Psyche, could be made entirely of metal and is worth an estimated $10,000 quadrillion. However, that's not the thing that makes it interesting. Scientists believe Psyche could be the metallic core remnant of a former planet and studying it could help us understand the core of our own planet.
