Mercury(II) sulfide, HgS, adopts the cinnabar structure described, and one additional structure, i.e. it is dimorphous. [16] Cinnabar is the more stable form, and is a structure akin to that of HgO : each Hg center has two short Hg−S bonds (each 2.36 Å ), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations).
An unusual feature of Mercury's surface is the numerous compression folds, or rupes, that crisscross the plains. These exist on the Moon, but are much more prominent on Mercury. [69] As Mercury's interior cooled, it contracted and its surface began to deform, creating wrinkle ridges and lobate scarps associated with thrust faults.
The interior of Caloris also harbors several unusual dark-rimmed craters, which are visible in this image. The MESSENGER science team is working with the 11-color images in order to gain a better understanding of what minerals are present in these rocks of Mercury's crust. The diameter of Mercury is about 4880 kilometers (3030 miles).

Mercury was a propellant for early ion engines in electric space propulsion systems. Advantages were mercury's high molecular weight, low ionization energy, low dual-ionization energy, high liquid density and liquid storability at room temperature. Disadvantages were concerns regarding environmental impact associated with ground testing and ...
The angle of the planets makes Mercury appear smaller—but it’s actually just farther away. (P.S. There’s a crude joke in here about size not mattering, but I’m trying not to reach for the ...
Mix mercury with sulfur to form aethiopes mineralis, a black compound of mercury sulfide. Heat this in a flask (the compound vaporizes and recondenses in the top of the flask). Break the flask. Collect the vermilion and grind it. When first created, the material is almost black. As it is ground, the red color appears.
