Planetary seismology is the study of seismic activity on other planets, moons, and celestial bodies within our solar system. This field involves using data collected from seismometers and other instruments to study the interior structure and composition of these bodies, as well as their tectonic activity and geological processes. By studying planetary seismology, scientists can gain insights into the formation and evolution of these celestial bodies and better understand their unique geophysical characteristics. This research area is crucial for advancing our understanding of planetary geology and the potential for habitability on other worlds.
