Research into the solar system, known as planetology or the planetary
sciences, covers a diverse section of the sciences, with areas of study
ranging between microscopic grains and the gas giant planets. This, combined
with the general comparisons with analogous systems on the Earth involves
interdisicplinary work. Research tends to be done by a combination of ground
based observations, remote spacecraft observations, and both experimental
and theoretical work based on Earth. It shares many interests with the Earth Sciences.
