In 1871, during his presidential address to the British Association in Edinburgh, Sir William Thompson (later Lord Kelvin) discussed the impact of two Earth-like bodies, asserting that "when two great masses come into collision in space, it is certain that a large part of each is melted" [see Arrhenius (1908, p. 218) for the complete quotation]. Although he did not go on to speculate about lunar origin, it must have been remarkable to see one of the creators of the bastions of nineteenth…

Theories of the origin of the solar system 1956- 1985

Attempts to find a plausible naturalistic explanation of the origin of the solar system began about 350 years ago but have not yet been quantitatively successful. The period 1956- 1985 includes the

The origin of the moon and the single-impact hypothesis III.

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

Chemical and isotopic consequences of lunar formation via giant impact

There is near consensus in the planetary science community that the origin of the Moon can be traced to a massive interplanetary collision between a roughly Mars-sized object and the growing Earth

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

Collision Chains among the Terrestrial Planets. III. Formation of the Moon

In the canonical model of Moon formation, a Mars-sized protoplanet “Theia” collides with proto-Earth at close to their mutual escape velocity v esc and a common impact angle ∼45°. The

The most widely accepted scenario for the formation of the Earth-Moon system involves a dramatic impact between the proto-Earth and some other cosmic body. Many features of the present-day Earth-Moon



Impact Vaporization and Lunar Origin

Theories for the origin of the moon fall into three broad categories, each of which suffers from particular difficulties. Capture hypotheses are limited by the low probability of a favorable

Orbital Eccentricity of Mercury and the Origin of the Moon

A NUMBER of mechanisms for the formation of the Moon have been suggested; fission of the Earth, precipitation in a hot gaseous silicate atmosphere, independent formation in orbit about the Earth, and

Lunar nodal tide and distance to the Moon during the Precambrian

The first direct determination of the lunar distance in the Precambrian is presented, interpreting a 23.3±0.3-yr periodicity preserved in a 2,500 Myr BP Australian banded iron formation as reflecting the climatic influence of the Lunar nodal tide, which has been detected with its modern 18.6-yrperiodicity in some modern climate records.

Origin of the Moon — Capture by gas drag of the Earth's primordial atmosphere

We propose a new scenario of the lunar origin, which is a natural extension of planetary formation processes studied so far by us in Kyoto. According to these studies, the Earth grew up in a gaseous

Origins of satellites

Satellites are an inevitable consequence of most plausible planetary accumulation processes. They can arise from gaseous or particulate circumplanetary disks, continuously fed during accretion of the

The interaction of the Cretaceous/Tertiary Extinction Bolide with the atmosphere, ocean, and solid Earth

The mechanics of large-scale (~10-km diameter) asteroidal, cometary, and meteoroid swarm impact onto a silicate Earth covered by water and a gas layer (atmosphere) demonstrate that only ~ 15% to ~ 5%
