A closer look at Psyche

Psyche is a potato-shaped asteroid that is about 142 miles (229 kilometers) across. It is located in the main asteroid belt between Mars and Jupiter. Psyche is one of the seven or eight metal-rich asteroids known to exist in the asteroid belt. Scientists believe that Psyche may be the exposed core of an early planet. This is because Psyche is similar in size to Mars and has a density that is consistent with a metal core. Psyche also has a weak magnetic field, which is further evidence that it may have a metal core.

One of the most intriguing aspects of Psyche is its composition, markedly different from the majority of asteroids that are primarily composed of rock or ice. Psyche is believed to be rich in iron and nickel, similar to the composition of Earth’s core. This suggests that Psyche may represent the stripped-down core of an early protoplanet, left behind after violent collisions and the removal of outer layers.

The Psyche spacecraft

The Psyche spacecraft, designed and built by NASA’s Jet Propulsion Laboratory (JPL), is a technological marvel poised to embark on a groundbreaking mission to unravel the mysteries of asteroid 16 Psyche.
