Laboratory simulations of the Vis-NIR spectra of comet 67P using sub-µm sized cosmochemical analogues

•Sub-micrometre mixes were made with coal, iron sulphide (pyrrhotite) and silicate.•Reflectance between 0.45-2.7µm was compared to mean VIRTIS/Rosetta spectra of 67P.•While pyrrhotite darkens the spectra, organics are needed to provide the red slope.•The type of the mixture (intimate, coating) influ...
