16 Psyche

Asteroid 16 Psyche, discovered on March 17, 1852, by the Italian astronomer Annibale de Gasparis, is an intriguing celestial body located in the asteroid belt between Mars and Jupiter. Psyche is particularly notable for its unique composition, speculated to consist predominantly of metallic iron and nickel. This metallic composition distinguishes it from most other asteroids, which typically have rocky or carbonaceous compositions. With an estimated diameter of approximately 226 kilometers (140 miles), Psyche orbits the Sun at an average distance of around 429 million kilometers (267 million miles) and completes its orbit in approximately 4.9 Earth years. The metallic nature of Psyche has led to significant interest, and NASA plans to explore this asteroid with the Psyche spacecraft, already launched and planned to arrive in August 2029. This mission aims to study Psyche's surface and composition in greater detail, offering insights into the origins of planetary cores and potentially unlocking secrets about the early solar system's formation.
