* Planetary Geologist: This is the most common and accurate term. Planetary geologists study the geology of celestial bodies, including planets, moons, asteroids, and meteorites.
* Astrogeologist: This term is sometimes used interchangeably with planetary geologist but can also refer to someone specifically studying the geological history and processes of extraterrestrial objects.
* Geochemist: Geochemists study the chemical composition and processes of rocks and minerals, including those found on other planets.
* Mineralogist: Mineralogists specialize in the identification and analysis of minerals, including those found in extraterrestrial samples.
Ultimately, the type of scientist who studies rocks on other planets depends on the specific area of research. For example, a planetary geologist might focus on the formation and evolution of planetary surfaces, while a geochemist might study the chemical composition of rocks to understand the history of a planet.
