In this brief summary, I present recent progress on our knowledge of the Giant Planets and Titan atmospheric composition, as well as the impact of this progress on our understanding of Solar System formation, and atmospheric chemistry.doi:10.1017/S1539299600017421T. Fouchet...
Chemically and structurally, Earth’sMoonis like the terrestrial planets, but most moons are in the outer solar system, and they have compositions similar to the cores of the giant planets around which they orbit. The three largest moons—Ganymede and Callisto in the jovian system, andTitanin t...
What planets are inner and outer? Mercury, Venus, Earth and Mars are the inner planets, whereas the outer planets of the solar system are Jupiter, Saturn, Uranus and Neptune. Why is Mars an inner planet? Mars is an inner planet because it is made up of rocks, orbits closer to the sun...
Surfaces, atmospheres and magnetospheres of the outer planets, their satellites and ring systems: Part XII 4.1.1 Science mission profile To measure the atmospheric composition, thermal and energy structure, clouds and dynamics requires in situ measurements by a probe carrying a mass spectrometer (atmo...
University of Zurich, explains. “This could be due to giant impacts on these planets that break off some of the outer, lighter materials, while the dense iron core remains,” according to the researcher. The results could therefore give the scientists clues about the history of the planets....
This large class of objects, the C asteroids, accounts for a progressively larger fraction of minor planets as one goes from the inner to the outer regions of the asteroid belt, a trend which has been interpreted as evidence of a decrease in effective condensation temperature in the original ...
The population of planets smaller than approximately 1.7 Earth radii (R⊕) is widely interpreted as consisting of rocky worlds, generally referred to as super-Earths. This picture is largely corroborated by radial velocity mass measurements for close-in super-Earths but lacks constraints at lower...
Planets and Moons A small fraction, about 0.2%, originates from other planets or moons. The most common are: Martian meteorites:These are pieces of rock blasted off the Martian surface by meteoroid impacts. Scientists can identify them by their unique chemical composition and trapped gases that ...
The problem of the internal structure of the Moon plays a special role in understanding its geochemistry and geophysics. The principal sources of informati
The mantle reaches all the way to just above the outer core at the Gutenberg discontinuity. Formation of the Mantle The formation of Earth consisted of violent impacts resulting in Earth being mostly molten. Differentiation of the layers of Earth happened because of the differences in density ...
