TL;DR: 16 Psyche Metal Assessment is a main entry in the 外星矿物知识引擎 database.
Spectroscopic and radar data strongly suggest a metallic surface composition. However, the interior structure (solid metal vs. rubble pile with metal fragments) remains unknown. The NASA Psyche mission (arrival 2029) will provide definitive composition data.
Resource
Iron-nickel-platinum group metals
Assessment Method
Ground-based spectroscopy, radar, Hubble UV observations
Estimated Value
Potentially largest metal resource in solar system
