Abstract: | Results of the optical observations of Mercury and the Moon confirm the close similarity of photometric properties of the bodies. Undoubtedly, the surface of Mercury, which is subjected to the same processes, is covered by a mantle of shattered rocks – the regolith. The structure of the reflecting layer determines the photometric and polarization characteristics of the surface of a planetary body. Despite the general similarity of the integral optical properties of the surfaces of Mercury and the Moon, specific characteristics of the media of these celestial bodies manifest themselves as identifiable differences in the details of the measured parameters: Mercury’s regolith is smoother than of the Moon, probably contains a greater fines fraction, and has greater maturity. |
