 "Planetary science
is the scientific study of
planets,
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 astronomy,
planetary geology (together with
geochemistry and
geophysics),
physical geography (geomorphology
and
cartography as applied to planets),
atmospheric science,
theoretical planetary science, and the study of
extrasolar planets. Allied disciplines include
space physics, when concerned with the effects of the
Sun
on the bodies of the Solar System, and
astrobiology."
