Extended Data Fig. 2: Spectral Comparison using the Mixture of Common Factor Analysers (MCFA) model.

From: Asteroid Kamo‘oalewa’s journey from the lunar Giordano Bruno crater to Earth 1:1 resonance

Extended Data Fig. 2

The latent scores are computed as a lower-dimensional representation of the reflectance spectrum, using the classy package51. The MCFA results suggest that Kamo‘oalewa is spectrally similar to lunar materials, but incompatible with any typical asteroid spectrum in public repositories.
