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
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
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.
Preliminary Results in Dynamical Simulations of Water Origins for Earth-Like Planets
In its gaseous and solid forms, water is present in the most distant galaxies, among the stars, in the Sun, in its planets and their satellites and ring systems, and in comets. In its liquid form, it

Delivery of Water and Volatiles to the Terrestrial Planets and the Moon
From modeling the evolution of disks of planetesimals under the influence of planets, it has been shown that the mass of water delivered to the Earth from beyond Jupiter’s orbit could be comparable


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
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
Distribution and Evolution of Water Ice in the Solar Nebula: Implications for Solar System Body Formation☆
Abstract Water is important in the solar nebula both because it is extremely abundant and because it condenses out at 5 AU, allowing all three phases of H 2 O to play a role in the composition and
Orbital Evolution of Asteroids during Depletion of the Solar Nebula
The pumping-up of inclinations and eccentricities caused by sweeping secular resonances in the asteroid belt is studied through numerical orbital integration and linear analysis. The present
Making the Terrestrial Planets: N-Body Integrations of Planetary Embryos in Three Dimensions
We simulate the late stages of terrestrial-planet formation using N-body integrations, in three dimensions, of disks of up to 56 initially isolated, nearly coplanar planetary embryos, plus Jupiter
Orbital Evolution of Planets Embedded in a Planetesimal Disk
The existence of the Oort comet cloud, the Kuiper belt, and plausible inefficiencies in planetary core formation all suggest that there was once a residual planetesimal disk of mass ∼10–100 M⊕ in the
