Are There Terrestrial Planets Lurking in the Outer Solar System? [PDF]
The Astrophysical Journal Letters, 2023 Motivated by recent measurements of the free-floating-planet mass function at terrestrial masses, we consider the possibility that the solar system may have captured a terrestrial planet early in its history.

Terrestrial Planet Formation: The Solar System and Other Systems [PDF]
Symposium - International Astronomical Union, 2004 Accretion of terrestrial planets and solid cores of jovian planets is discussed, based on the results of our N-body simulations. Protoplanets accrete from planetesimals through runaway and oligarchic growth until they become isolated. The isolation mass of protoplanets in terrestrial planet region is about 0.2 Earth mass, which suggests that in the ...

Constraining the Formation of the Four Terrestrial Planets in the Solar System [PDF]
The Astrophysical Journal, 2019 Abstract To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in the literature on the likelihood of forming planet analogs simultaneously in the same system (analog system). To address this issue,

Can narrow discs in the inner Solar system explain the four terrestrial planets? [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT A successful Solar system model must reproduce the four terrestrial planets. Here, we focus on (1) the likelihood of forming Mercury and the four terrestrial planets in the same system (a 4-P system); (2) the orbital properties and masses of each terrestrial planet; and (3) the timing of Earth’s last giant impact and the mass ...

Terrestrial planet formation in extra-solar planetary systems [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractTerrestrial planets form in a series of dynamical steps from the solid component of circumstellar disks. First, km-sized planetesimals form likely via a combination of sticky collisions, turbulent concentration of solids, and gravitational collapse from micron-sized dust grains in the thin disk midplane.

Atmospheric Escape from Solar System Terrestrial Planets and Exoplanets [PDF]
Annual Review of Earth and Planetary Sciences, 2015 It has been known for decades that atmospheric escape is important for the evolution of terrestrial planets in the Solar System, although exactly how atmospheric escape changes the atmospheres of these bodies is still hotly debated. Rapidly increasing numbers of exoplanet observations provide new targets against which atmospheric escape models are ...

Did the terrestrial planets of the Solar System form by pebble accretion? [PDF]
Earth and Planetary Science LettersThe dominant accretion process leading to the formation of the terrestrial planets of the Solar System is a subject of intense scientific debate. Two radically different scenarios have been proposed. The classic scenario starts from a disk of planetesimals which, by mutual collisions, produce a set of Moon to Mars-mass planetary embryos.
