This simple difference in formation environment dictates whether a world becomes a dense, compact terrestrial planet or a sprawling, gaseous giant. Farther out, in the cooler regions of the disc of dust and gas, these light elements could accumulate on a much grander scale.
Exploring Terrestrial Planets Geology and Surface Diversity
Mercury: The smallest and innermost planet, with a large iron core and a tenuous exosphere. Mars: A cold, desert world with evidence of a wet past and the tallest volcano in the solar system.
Terrestrial Planets: The Solid Worlds Terrestrial planets, named after Terra, the Latin word for Earth, are defined by their solid, rocky surfaces and relatively high densities. Close to the sun, where intense heat prevented light gases from condensing, the planets formed dense cores of metal and rock.
Diverse Geology of Terrestrial Planets in Our Solar System
They are massive, cold, and possess complex atmospheric systems that dwarf anything seen on the terrestrial worlds. Because they originated so far from the sun, the frost line allowed them to capture vast amounts of these light gases, resulting in planets that are mostly fluid rather than solid.
