Abstract— In the primordial solar system, the most plausible sources of the water accreted by the Earth were in the outer asteroid belt, in the giant planet regions, and in the Kuiper Belt. We investigate the implications on the origin of Earth's water of dynamical models of primordial evolution of solar system bodies and check them with respect to chemical constraints. We find that it is plausible that the Earth accreted water all along its formation, from the early phases when the solar… 
The Delivery of Water During Terrestrial Planet Formation
The planetary building blocks that formed in the terrestrial planet region were likely very dry, yet water is comparatively abundant on Earth. Here we review the various mechanisms proposed for the

The formation of the Earth as a planet was a large stochastic process in which the rapid assembly of asteroidal-to-Mars-sized bodies was followed by a more extended period of growth through
Origins of Sea Water on the Earth
Although the mass of oceans on the Earth is a tiny fraction (0.023 wt%) of the bulk Earth mass, the existence of oceans is sufficient to distinguish the Earth from the other planets in the solar
Origin of water in the terrestrial planets
Abstract— I examine the origin of water in the terrestrial planets. Late‐stage delivery of water from asteroidal and cometary sources appears to be ruled out by isotopic and molecular ratio
Origin and evolution of the atmospheres of early Venus, Earth and Mars
We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the time when their accreting bodies were released from the protoplanetary disk a few million years after the

We examine the origin of water in the terrestrial planets. We list various geochemical measurements that may be used to discriminate between different endogenous and exogenous sources of water. Late
Early accretion of water in the inner solar system from a carbonaceous chondrite–like source
Measurements of the hydrogen isotopic composition of the mineral apatite in eucrite meteorites show that Vesta contains the same hydrogen isotopy composition as that of carbonaceous chondrites, and suggest that Earth received most of its water relatively early from chondrite-like bodies.


Ejection of Bodies from the Solar System in the Course of the Accumulation of the Giant Planets and the Formation of the Cometary Cloud
The theory of planetary accumulation leads quite definitely to the conclusion that the formation of Oort’s cometary cloud is the result of ejection of bodies to the outermost parts of the solar
Formation of the Giant Planets by Concurrent Accretion of Solids and Gas
New numerical simulations of the formation of the giant of the second phase. planets are presented, in which for the first time both the gas and The actual rates at which the giant planets accreted
The Late Asteroidal and Cometary Bombardment of Earth as Recorded in Water Deuterium to Protium Ratio
The deuterium to protium (D/H) ratio of the deep mantle may be a remnant of the hydrogen isotopic composition of Earth forming planetesimals, which later evolved as a result of the late accretion of
Comets, impacts, and atmospheres.
A mixture of three basic types of comets appears capable of accounting for the observed volatile inventories on Venus, Earth, and Mars, with the caveat that impact erosion is necessary to explain the present condition of the martian atmosphere.
Irradiated interplanetary dust particles as a possible solution for the deuterium/hydrogen paradox of Earth's oceans.
It is suggested that solar wind-implanted hydrogen on interplanetary dust particles (IDPs) provided the necessary low-D/H component of Earth's water inventory.
Orbital and temporal distributions of meteorites originating in the asteroid belt
Abstract— The recent discovery of the importance of Sun‐grazing phenomena dramatically changed our understanding of the dynamics of objects emerging from the asteroid belt via resonant phenomena. The
Structure and Transport in the Solar Nebula from Constraints on Deuterium Enrichment and Giant Planets Formation
Abstract A simplified analytical model of an evolutionary nebula is used to generate temperature–density radial profiles following the procedure elaborated by Dubrulle ( Icarus 106 , 59, 1993). Each
