Top: observed mean reflectance spectrum of Apophis and Cruithne from the MITHNEOS survey (Binzel et al. 2019; Marsset et al. 2022). Their comparison to taxonomic classes (S, Sq, Q) shows that Apophis is Sq type and Cruithne is Q type. Bottom: same spectra after dereddening (Brunetto et al. 2006); we note the applicability in the visible of this simplified, exp(-C_S/λ) model is limited. Their comparison to ordinary chondrite classes (H, L, LL) shows that both asteroids are LL-like.
