Planetary scientists work to improve understanding of the planets, satellites and smaller bodies in the solar system through studying the atmosphere, surface and interior of planets. These scientists work to understand the origins of planets and the physical processes at work by using radar to determine the physical characteristics of asteroids. Some planetary scientists also search 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. Source
