Planetary scientists
Planetary scientists work to improve our understanding of the planets, satellites and smaller bodies in the solar system. By studying the atmospheres, surfaces and interiors of planets, researchers can get clues to the origins and mechanics of our own home planet. Examples of these studies focus on understanding the origins of planets, using radar to determine the physical characteristics of asteroids, and searching for asteroids that may pose a hazard to Earth. Research is carried out in the laboratory, from astronomical facilities throughout the world, and from spacecraft and landers.
Scientists characterize distant giant planets in our solar system and also discover new giant planets in distant galaxies. 
Planetary atmosphere studies are conducted on most planets and planetary bodies in the solar system. 
Geoscience and geophysics research at JPL focuses on the study of solid bodies in our solar system, such as Venus and Mars. 
Efforts in radio science at JPL have contributed to significant findings in researching planetary rings, atmospheres, and surfaces. 
Near earth objects and small planetary bodies are important to researchers as the look for clues to planetary formation and as they catalog asteroids and comets close to earth. 
Europa, Titan, and Enceladus are some of the icy bodies in our solar system that researchers are currently studying as they search for life.
