Abstract from DBPedia
    Planetary science or, more rarely, planetology, is the scientific study of planets (including Earth), moons, and planetary systems (in particular those of the Solar System) and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science, but which now incorporates many disciplines, including planetary geology (together with geochemistry and geophysics), cosmochemistry, atmospheric science, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve a combination of space exploration, predominantly with robotic spacecraft missions using remote sensing, and comparative, experimental work in Earth-based laboratories. The theoretical component involves considerable computer simulation and mathematical modelling. Planetary scientists are generally located in the astronomy and physics or Earth sciences departments of universities or research centres, though there are several purely planetary science institutes worldwide. There are several major conferences each year, and a wide range of peer-reviewed journals. Some planetary scientists work at private research centres and often initiate partnership research tasks.

    惑星科学(わくせいかがく、planetary science)は、惑星について研究する学問である。地球科学と天文学をつなぐ学問であるといえるが、天文学が中学校・高等学校においては地学分野に、大学では物理学の一分野として位置づけられているのに対し、惑星科学は中学・高校・大学のいずれでも地学=地球科学の一分野とされている。それは惑星科学が地球科学の他惑星への応用という一面を持っているからである。 なお、惑星科学のうち特に物理学的手法を用いるものを惑星物理学と呼ぶ。
