The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
Planetary Science – study of planets, moons, and planetary systems. Atmospheric science – study of atmospheres and weather. Exoplanetology – various planets outside of the Solar System; Planetary formation – formation of planets and moons in the context of the formation and evolution of the Solar System.
Currently, the responsibility for naming minor planets lies with the Working Group Small Bodies Nomenclature (WGSBN, originally the Committee Small Bodies Nomenclature, CSBN, and before that the Minor Planet Names Committee, MPNC), which is composed of 15 members, 11 of whom are voting members, while the other four are representatives for the ...
Mad Planets is a multidirectional shooter released as an arcade video game in 1983 by Gottlieb. The player controls a spaceship, which can be moved and rotated independently, to fend off angry planets and moons attacking from all sides. It was designed and programmed by Kan Yabumoto [3] [4] with art by Jeff Lee and sound by David D. Thiel. [3]
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
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 ...
