An Intra-Mercurial Planet [PDF]
Nature, 1876 THE discussion as to the existence of a planet within the orbit of Mercury leads me to communicate an observation made many years ago, which I believe nothing but the existence of an unknown planet between us and the sun can explain. On Sunday, January 29, 1860, the sun rose in a fog in London, so that he could be steadily looked at as if through a ...

The Dynamical Consequences of a Super-Earth in the Solar System
The Planetary Science Journal, 2023 Placing the architecture of the solar system within the broader context of planetary architectures is one of the primary topics of interest within planetary science. Exoplanet discoveries have revealed a large range of system architectures, many of which

A sub-Mercury-sized exoplanet [PDF]
, 2013 Since the discovery of the first exoplanets, it has been known that other planetary systems can look quite unlike our own. Until fairly recently, we have been able to probe only the upper range of the planet size distribution, and, since last year, to ...

Catastrophic Evaporation of Rocky Planets [PDF]
, 2013 Short-period exoplanets can have dayside surface temperatures surpassing 2000 K, hot enough to vaporize rock and drive a thermal wind. Small enough planets evaporate completely.

A Reanalysis of the Composition of K2-106b: An Ultra-short-period Super-Mercury Candidate
The Astronomical Journal, 2023 We present a reanalysis of the K2-106 transiting planetary system, with a focus on the composition of K2-106b, an ultra-short-period, super-Mercury candidate. We globally model existing photometric and radial velocity data and derive a planetary mass and

How terrestrial planets traverse spin-orbit resonances: A camel goes through a needle's eye
, 2012 The dynamical evolution of terrestrial planets resembling Mercury in the vicinity of spin-orbit resonances is investigated using comprehensive harmonic expansions of the tidal torque taking into account the frequency-dependent quality factors and Love ...

Has Kronos Devoured Planet Nine and Its Epigones?
UniverseThe Planet Nine hypothesis encompasses a body of about 5–8 Earth’s masses whose orbital plane would be inclined to the ecliptic by one or two tens of degrees and whose perihelion distance would be as large as about 240–385 astronomical units. Recently, a

Addressing the statistical mechanics of planet orbits in the solar system
, 2017 The chaotic nature of planet dynamics in the solar system suggests the relevance of a statistical approach to planetary orbits. In such a statistical description, the time-dependent position and velocity of the planets are replaced by the probability ...

Evolution of Mercury’s Volatile-bearing Crust within Raditladi Basin
The Planetary Science JournalMercury’s surface presents significant challenges for understanding planetary volatile distribution. Previous studies have identified features including hollows, flows, and chaotic terrains as associated with the presence of volatiles.
