The Moon forming giant impact marks the end of the main stage of Earth’s accretion and sets the stage for the subsequent evolution of our planet. The giant impact theory has been the accepted model of lunar origin for 40 years, but the parameters of the impact and the mechanisms that led to the formation of the Moon are still hotly debated. Here we review the principal geochemical observations that constrain the timing and parameters of the impact, the mechanisms of lunar formation, and the… 
Formation of Venus, Earth and Mars: Constrained by Isotopes
Here we discuss the current state of knowledge of terrestrial planet formation from the aspects of different planet formation models and isotopic data from Hf-W, U-Pb, lithophile-siderophile
Tidal Evolution of the Earth–Moon System with a High Initial Obliquity
A giant-impact origin for the Moon is generally accepted, but many aspects of lunar formation remain poorly understood and debated. Ćuk et al. proposed that an impact that left the Earth–Moon system
Did Earth Eat Its Leftovers? Impact Ejecta as a Component of the Late Veneer
The presence of highly siderophile elements in Earth’s mantle indicates that a small percentage of Earth’s mass was delivered after the last giant impact in a stage of “late accretion.” There is
A Review of the Lunar 182Hf-182W Isotope System Research
In recent years, the extinct nuclide 182Hf-182W system has been developed as an essential tool to date and trace the lunar origin and evolution. Despite a series of achievements, controversies and
Long‐Term Earth‐Moon Evolution With High‐Level Orbit and Ocean Tide Models
Tides and Earth‐Moon system evolution are coupled over geological time. Tidal energy dissipation on Earth slows Earth′ s rotation rate, increases obliquity, lunar orbit semi‐major axis and
The Exosphere as a Boundary: Origin and Evolution of Airless Bodies in the Inner Solar System and Beyond Including Planets with Silicate Atmospheres
In this review we discuss all the relevant solar/stellar radiation and plasma parameters and processes that act together in the formation and modification of atmospheres and exospheres that consist


On the origin of Earth's Moon
The Giant Impact is currently accepted as the leading theory for the formation of Earth's Moon. Successful scenarios for lunar origin should be able to explain the chemical composition of the Moon
Terrestrial magma ocean origin of the Moon
A conceptual framework for the origin of the Moon must explain both the chemical and the mechanical characteristics of the Earth–Moon system to be viable. The classic concept of an oblique giant
The Origin of the Moon Within a Terrestrial Synestia
The giant impact hypothesis remains the leading theory for lunar origin. However, current models struggle to explain the Moon's composition and isotopic similarity with Earth. Here we present a new
Geochemical arguments for an Earth-like Moon-forming impactor
An inversion method is presented to calculate the Hf/W ratios and ϵ182W values of the proto-Earth and impactor mantles for a given Moon-forming impact scenario.
Oxygen isotopic evidence for accretion of Earth’s water before a high-energy Moon-forming giant impact
It is shown that the bulk of Earth’s water was delivered before the high-energy collision that led to the formation of the Moon and not later, as often proposed.
The isotopic nature of the Earth’s accreting material through time
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.
Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact
The results indicate that the late veneer impactors had an average Δ′17O within approximately 1 per mil of the terrestrial value, limiting possible sources for this late addition of mass to the Earth-Moon system.
