Theoretical planetology, also known as theoretical planetary science [3] is a branch of planetary sciences that developed in the 20th century. [4] Scientific models supported by laboratory experiments are used to understand the formation, evolution, and internal structure of planets.
Planetary science (or more rarely, planetology) is the scientific study of planets ... There are interrelated observational and theoretical branches of planetary science.
Like theoretical chemical astronomy, the lines of conceptual understanding between theoretical astrophysics and theoretical physical astronomy are often blurred, but, again, there are subtle differences between these two sciences. Theoretical physics as applied to astronomy seeks to find new ways to observe physical phenomena in celestial ...
Planetary science is the study of the assemblage of planets, moons, dwarf planets, comets, asteroids, and other bodies orbiting the Sun, as well as extrasolar planets. The Solar System has been relatively well-studied, initially through telescopes and then later by spacecraft. This has provided a good overall understanding of the formation and ...
This planetary formation hypothesis represents an extension of the Whole-Earth Decompression Dynamics (WEDD) model, [24] which includes natural nuclear-fission reactors in planetary cores; Herndon expounds upon it in eleven articles in Current Science from 2005 to 2013 and five books published from 2008 to 2012. He refers to his model as ...
A and B, two super-Earth (or even supergiant) planets theorized by Michael Woolfson as part of his Capture theory on Solar System formation. Originally the Solar System's two innermost planets, these two collided, ejecting A (save its moons Mars, the Moon, Pluto, and the other dwarf planets) out of the Solar System and shattering B to form the ...
Epicyclic theory, in part, sought to explain this behavior. The inferior planets were always observed to be near the Sun, appearing only shortly before sunrise or shortly after sunset. Their apparent retrograde motion occurs during the transition between evening star into morning star, as they pass between the Earth and the Sun.
