Comparative planetology is a scientific discipline in which researchers seek to understand the planets by comparing their similarities and examining their differences. Some planets have similarities because the materials of which they are made and the processes that have shaped them are similar. However, each planet has a unique character due to the intensity and length of time the processes have operated.
