Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ices, and, for the Earth, liquid water. Each layer has different dominant elements (e.g., increasing iron content with depth and increasing oxygen content to the surface). Chondrites, the building blocks of the terrestrial planets, have mass and atomic proportions of oxygen, iron, magnesium, and silicon totaling ≥ 90…

Iron Silicate Fractionation and the Origin of Mercury
An Earth-sized exoplanet with a Mercury-like composition
Earth, Venus, Mars and some extrasolar terrestrial planets1 have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle2. At the inner frontier
The Chemical Composition of Mercury
The chemical composition of a planetary body reflects its starting conditions modified by numerous processes during its formation and geological evolution. Measurements by X-ray, gamma-ray, and
On the Probability That a Rocky Planet’s Composition Reflects Its Host Star
The bulk density of a planet, as measured by mass and radius, is a result of planet structure and composition. Relative proportions of iron core, rocky mantle, and gaseous envelopes are degenerate
PHOTOPHORETIC SEPARATION OF METALS AND SILICATES: THE FORMATION OF MERCURY-LIKE PLANETS AND METAL DEPLETION IN CHONDRITES
Mercury's high uncompressed mass density suggests that the planet is largely composed of iron, either bound within metal (mainly Fe-Ni) or iron sulfide. Recent results from the MESSENGER mission to
TEMPERATURES IN PROTOPLANETARY DISKS
▪ Abstract Observations of suspected planet-forming disks provide estimates of protoplanetary disk masses, surface temperatures, and the rate at which mass is infalling onto the disks. Analyses of
The composition of Mars
The isotopic nature of the Earth’s accreting material through time
TLDR
It is shown that elements with distinct affinities for metal can be used to decipher the isotopic nature of the Earth’s accreting material through time, and indicates that the giant impactor that formed the Moon probably had an isotopic composition similar to that of theEarth, hence relaxing the constraints on models of lunar formation.
