Spectral Constraints on the Surface Material of Asteroid (469219) Kamoʻoalewa
Recent JWST observations reveal that the Earth’s quasi-satellite (469219) Kamoʻoalewa possesses a high geometric albedo and a flat near-infrared spectrum, in contrast with earlier ground-based observations, posing new challenges to its compositional identification. This study evaluates the potential surface composition...
