Solar system terrestrial planets as a research area focuses on the comparative study of Mercury, Venus, Earth, and Mars to understand the formation, differentiation, and evolution of rocky planets. It integrates planetary geology, geophysics, geochemistry, atmospheric science, and orbital dynamics to investigate crust–mantle–core structures, volcanic and tectonic processes, surface–atmosphere interactions, and volatile and climate histories. The field relies heavily on spacecraft missions, remote sensing, in situ measurements, laboratory analyses of analog materials, and numerical modeling to constrain accretion processes, interior dynamics, habitability conditions, and the broader context of terrestrial exoplanets.
Southwest Research Institute has collaborated with Yale University to summarize the scientific community's notable progress in advancing the understanding of the formation and evolution of the inner rocky planets, the so-called ...

Comets that have hit Earth have been a mixed bag. Early in Earth's history, during the solar system's chaotic beginning, they were likely the source of our planet's water, ultimately making up about 0.02% of the planet's ...
The solar system consists of our star, the sun, and everything bound to it by gravity: the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, along with dwarf planets like Pluto, dozens of moons, and ...
