A simple metric can be used to determine whether a planet or exoplanet can clear its orbital zone during a characteristic time scale, such as the lifetime of the host star on the main sequence. This criterion requires only estimates of star mass, planet mass, and orbital period, making it possible to immediately classify 99% of all known exoplanets. All eight planets and all classifiable exoplanets satisfy the criterion. This…

Towards a Classification Scheme for the Rocky Planets based on Equilibrium Thermodynamic Considerations
A classification scheme for rocky planets is proposed, based on a description of the Earth System in terms of the Landau-Ginzburg Theory of phase transitions. Three major equilibrium states can be
The Moon Meets All Requirements of the IAU Definition for “Planet”
The Earth-Moon system has often been characterized as having some characteristics of a “double planet” system. It is demonstrated that while the orbital barycenter of the Earth-Moon pair lies inside
Long-term Dynamical Stability in the Outer Solar System. I. The Regular and Chaotic Evolution of the 34 Largest Trans-Neptunian Objects
We carried out an extensive analysis of the stability of the outer solar system, making use of the frequency analysis technique over short-term integrations of nearly 100,000 test particles, as well
Searching for hot Jupiter transits around cool stars
In this thesis, I describe the search for transiting hot Jupiters with a focus on cool dwarfs, low-mass main-sequence stars. I detail the results of our Pan-Planets survey and the necessary follow-up

Abstract The distribution of diameters and orbital distances from the parent body of 156 named moons of the planets in the Solar System is not random. All 11 moons with diameters larger than
Solar System Physics for Exoplanet Research
Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos - the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the
Chime’s Laws for Distribution of Planets, Moons and Planetary Ring-Systems: Critical Examination of Their Predictions and the Implications
Study Aim: The problem as to whether planets, moons and planetary ring-systems are randomly or non-randomly distributed in the solar system has not been resolved. In this article, the predictions of
Erosive Hit-and-Run Impact Events: Debris Unbound
Abstract Erosive collisions among planetary embryos in the inner solar system can lead to multiple remnant bodies, varied in mass, composition and residual velocity. Some of the smaller, unbound

TLDR
The proposed definition dispenses with upper and lower mass limits for a planet and reflects the tendency of disk evolution in a mature system to produce a small number of relatively large bodies (planets) in nonintersecting or resonant orbits, which prevents collisions between them.

The Stability of Multi-Planet Systems
A system of two small planets orbiting the Sun on low-eccentricity, low-inclination orbits is stable with respect to close encounters if the initial semi-major axis difference, Δ, measured in mutual

The Kepler Mission has discovered thousands of planets with radii $<4\ R_\oplus$, paving the way for the first statistical studies of the dynamics, formation, and evolution of these sub-Neptunes and

ARE PLANETARY SYSTEMS FILLED TO CAPACITY? A STUDY BASED ON KEPLER RESULTS
We used a sample of Kepler candidate planets with orbital periods less than 200 days and radii between 1.5 and 30 Earth radii (R ⊕) to determine the typical dynamical spacing of neighboring planets.

We analyze the transit timing variations (TTV) obtained by the Kepler mission for 22 sub-Jovian planet pairs (19 published, 3 new) that lie close to mean motion resonances. We find that the TTV

TLDR
Kepler has provided us with the authors' first look at the typical characteristics of planets and planetary systems for planets with sizes as small as, and orbits as large as, those of Earth.
