Geologists.
Cats
For the same reasons they do so on earth. To pinpoint locations.
the solar system is 4.6 billion years old.
A planetary geologist studies rocks on other planets. They analyze the composition, structure, and history of rocks to understand the geology of other planets in our solar system.
Geologists primarily study the Earth, focusing on its structure, composition, and processes. They investigate the formation of rocks, minerals, and natural resources, as well as geological hazards such as earthquakes and volcanic eruptions. Additionally, some geologists may also study other planetary bodies in our solar system.
Planetary geologists study the geology of planets, moons, and other celestial bodies in order to understand their formation, composition, and evolution. They help us gain insights into the history and processes that have shaped these worlds, which can have implications for understanding our own planet and the possibility of life beyond Earth.
The plural of geologist is geologists. As in "the geologists are studying the meteor sample".
geologists!!! ... "biologists" not "geologists"...
That would be a geologist? Or if you wanted a name: http://en.wikipedia.org/wiki/List_of_geologists
There are different types of geologists that study oil exploration, mineral exploration and mineral mining. There are also engineering geologists.
Geologists don't use rocks, they study them.
