Spectroscopic similarities of 1999 JD₆ and others. Top panel: spectra of 1999 JD₆ (red circles) and the Barbarians (172) Baucis (green squares), (234) Baraba (cyan diamonds), (679) Pax (blue crosses), and the range of K type (purple triangles) and L type (black pluses) according to the Bus-DeMeo classification (Demeo et al. 2009; Binzel et al. 2019). The spectra refer to textual data obtained from MITHNEOS¹. Bottom panel: compares the spectra of the CV3-type Allende (cyan crosses) and CO3-type Lance (green pluses) meteorites with those of 1999 JD₆ (red and blue circles). The 1999 JD₆ spectra are multiplied by the albedo within the literature values that best match the respective meteorite data. At the side where the wavelength is longer than 0.6 μm, it matches Allende well, while at the blue side, Lance is matched well. The scaled spectra of the meteorites were obtained from the RELAB² database.
