The Moon is the fifth largest satellite in the Solar System.It is larger than any of the known dwarf planets and is the largest (and most massive) satellite relative to its parent planet. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar.

MESSENGER was It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE). The actual brightness of sunlight that would be observed at the surface also depends on the presence and composition of an atmosphere.For example, Venus's thick atmosphere reflects more than 60% of the solar light it receives. This surface composition may hold clues to the moon's potential as a habitable world. The first images of Mercury revealed a cratered, rocky planet that closely resembled Earth's moon.

Owens Corning has solutions for your building & remodeling needs. But still, Venus is hotter than Mercury, which is due to the former's distinctive atmospheric composition. Dental amalgam is a liquid mercury and metal alloy mixture used in dentistry to fill cavities caused by tooth decay.
