Analysis of planetary surfaces and surface features is a major component of planetary science. Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a ...
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 ...
PNLF – (astrophysics terminology) Planetary Nebula Luminosity Function, the density of planetary nebula as a function of their luminosity; PNN – (celestial object) planetary nebula nucleus, the central star in a planetary nebula; PNNV – (celestial object) planetary nebula nucleus variable, a variable star in the center of a planetary nebula

Planetary Science – study of planets, moons, and planetary systems. Atmospheric science – study of atmospheres and weather. Planetary geology; Planetary oceanography; Exoplanetology – various planets outside of the Solar System; Astrochemistry – studies the abundance and reactions of molecules in the Universe, and their interaction with ...
Planetary geology, alternatively known as astrogeology or exogeology, is a planetary science discipline concerned with the geology of celestial bodies such as planets and their moons, asteroids, comets, and meteorites.
Some opponents of the definition have claimed that "clearing the neighbourhood" is an ambiguous concept. Mark Sykes, director of the Planetary Science Institute in Tucson, Arizona, and organiser of the petition, expressed this opinion to National Public Radio. He believes that the definition does not categorize a planet by composition or ...
