"It 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 the processes of their formation."
The study of planets, their moons, and other bodies in the Solar System.
"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...planetary geology, cosmochemistry, atmospheric science, physics, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology."
"It originally grew from astronomy and Earth science."
"Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology."
"Observational research can involve combinations 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 modeling."
"Planetary scientists are generally located in the astronomy and physics or Earth sciences departments of universities or research centers."
"Yes, they generally study one of the Earth sciences, astronomy, astrophysics, geophysics, or physics at the graduate level and concentrate their research in planetary science disciplines."
"There are several purely planetary science institutes worldwide."
"Some planetary scientists work at private research centers and often initiate partnership research tasks."
"There are several major conferences each year."
"There is a wide range of peer-reviewed journals."
"Planetary geology, cosmochemistry, atmospheric science, physics, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology."
"Yes, Earth is included in the study of planetary science."
"[Planetary science] aiming to determine their composition, dynamics, formation, interrelations, and history."
"It studies objects ranging in size from micrometeoroids to gas giants."
"...astronomy, astrophysics, geophysics, or physics."
"Astrobiology is an allied discipline of planetary science, focusing on the search for life beyond Earth."
