Earth and Terrestrial Planet Formation

open access: yesarXiv: Earth and Planetary Astrophysics, 2015
The growth and composition of Earth is a direct consequence of planet formation throughout the Solar System. We discuss the known history of the Solar System, the proposed stages of growth and how the early stages of planet formation may be dominated by ...

The Terrestrial Planet Finder [PDF]

open access: green2001 IEEE Aerospace Conference Proceedings (Cat. No.01TH8542), 2002
The Terrestrial Planet Finder (TPF) is a space-based astronomical telescope that will combine high sensitivity and spatial resolution to detect and characterize /spl sim/150 planetary systems within 15 pc of our Sun. In a five-year mission, currently expected to commence in 2012, TPF will look for the atmospheric signatures of life using the methods of

Terrestrial planet formation. [PDF]

open access: yesProc Natl Acad Sci U S A, 2011
Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets.

Formation of Terrestrial Planets [PDF]

open access: yesProceedings of the International Astronomical Union, 2018
The past decade has seen major progress in our understanding of terrestrial planet formation. Yet key questions remain. In this review we first address the growth of 100 km-scale planetesimals as a consequence of dust coagulation and concentration, with current models favoring the streaming instability.

Building Terrestrial Planets [PDF]

open access: yesAnnual Review of Earth and Planetary Sciences, 2012
This article reviews our current understanding of terrestrial planet formation. The focus is on computer simulations of the dynamical aspects of the accretion process. Throughout the review, we combine the results of these theoretical models with geochemical, cosmochemical, and chronological constraints to outline a comprehensive scenario of the early

Mercury’s Hidden Past: Revealing a Volatile-dominated Layer through Glacier-like Features and Chaotic Terrains

open access: yesThe Planetary Science Journal, 2023
The discovery of global elemental volatile compositions, sublimation hollows, and chaotic terrains has significantly reshaped our understanding of Mercury’s geology.

Migration of comets to the terrestrial planets [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2006
AbstractWe studied the orbital evolution of objects with initial orbits close to those of Jupiter-family comets (JFCs), Halley-type comets (HTCs), and long-period comets, and the probabilities of their collisions with the planets. In our runs the probability of a collision of one object with the Earth could be greater than the sum of probabilities for ...
