Origin of the Moon in a giant impact near the end of the Earth's formation
This work reports a class of impacts that yield an iron-poor Moon, as well as the current masses and angular momentum of the Earth–Moon system, and suggests that the Moon formed near the very end of Earth's accumulation. Expand
Simulations of a late lunar-forming impact
Abstract Results of about 100 hydrodynamic simulations of potential Moon-forming impacts are presented, focusing on the “late impact” scenario in which the lunar forming impact occurs near the veryExpand
Formation of the Galilean Satellites: Conditions of Accretion
We examine formation conditions for the Galilean satellites in the context of models of late-stage giant planet accretion and satellite-disk interactions. We first reevaluate the current standard, inExpand
Forming a Moon with an Earth-like Composition via a Giant Impact

  • 23 November 2012
Computer simulations show that a giant impact on early Earth could lead to a Moon with a composition similar to Earth’s, and simulate impacts involving larger impactors than previously considered that can produce a disk with the same composition as the planet's mantle, consistent with Earth-Moon compositional similarities.

A common mass scaling for satellite systems of gaseous planets
It is shown that the overall properties of the satellite systems of Jupiter, Saturn and Uranus arise naturally, and it is suggested that similar processes could limit the largest moons of extrasolar Jupiter-mass planets to Moon-to-Mars size. Expand
Dynamics of Lunar Formation
▪ Abstract The giant impact theory is the leading hypothesis for the origin of the Moon. This review focuses on dynamical aspects of an impact-induced lunar formation, in particular those areas thatExpand
On the Character and Consequences of Large Impacts in the Late Stage of Terrestrial Planet Formation
Abstract We perform three-dimensional N-body integrations of the final stages of terrestrial planet formation. We report the results of 10 simulations beginning with 22–50 initial planetary embryosExpand
A Giant Impact Origin of Pluto-Charon

  • 28 January 2005
Hydrodynamic simulations are used to demonstrate that the formation of Pluto-Charon by means of a large collision is quite plausible, and suggest that collisions between 1000-kilometer-class objects occurred in the early inner Kuiper belt. Expand
Thermal and Magmatic Evolution of the Moon
As with all science, our continually developing concepts of lunar evolution are firmly tied to both new types of observations and the integration of these observations to the known pool of data. ThisExpand
It is generally believed that Charon was formed as a result of a large, grazing collision with Pluto that supplied the Pluto-Charon system with its high angular momentum. It has also been proposedExpand
