Justitia compared to two B-class asteroids. A JWST/NIRSpec spectrum of Polana and an OSIRIS-REx spectrum of Bennu are close visual matches to Justitia, with the absorption centered near 2.7 μm in Polana and Bennu and partially present in Justitia, indicating a magnesium-rich phyllosilicate composition and the absorption near 3.4 μm in all three spectra indicating organic materials. The spectrum of Bennu is from X. D. Zou et al. (2021) and that of Polana is from A. Arredondo et al. (2025), and their data can be obtained at MAST (A. Arredondo 2025).
