TWDK Planetology Planetary Science doodle by Giles Meakin

Planetary Science, or Planetology, is a rapidly growing branch of science which describes the study of planets, celestial objects that are like planets, and anything which affects their shape, composition, appearance, or behaviour. As the study of planets includes the study of their structure and composition, atmosphere and climate cycles, their natural satellites and their interactions and relations with them and their star, planetary science overlaps greatly with some of the more traditional scientific disciplines.

The planet we know best is, of course, the one we are living on. Other planets can be studied remotely, using telescopes to observe them from a distance, while Space agencies around the world send robotic spacecraft to orbit, fly past or land on our planetary neighbours, and a dozen men have visited the moon.
