terrestrialmass

Terrestrial mass refers to the mass of planets that are primarily composed of silicate rocks and metals. These planets, also known as terrestrial planets or rocky planets, are distinguished from gas giants or ice giants by their solid surfaces and relatively high densities. The terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars. Their formation is thought to involve the accretion of planetesimals in the inner solar system, where temperatures were too high for volatile compounds like water and methane to condense. Consequently, these planets are rich in heavier elements. The Moon, while a natural satellite, is often discussed in the context of terrestrial planets due to its rocky composition and similar formation processes to early terrestrial planet bodies. Understanding terrestrial mass is crucial for comparative planetology, allowing scientists to compare the formation, evolution, and geological characteristics of different rocky worlds within and beyond our solar system. The internal structure of terrestrial planets typically consists of a metallic core, a silicate mantle, and a crust. Their masses vary significantly, with Earth being the most massive terrestrial planet in our solar system.
