radar astronomy

Radar astronomy is a technique used to study celestial objects like planets, asteroids, and comets by bouncing radar signals off them. Scientists send radio waves from Earth, which travel through space and hit these objects. When the radar waves reflect back, they provide valuable information about the object's distance, size, shape, surface texture, and motion. This method allows researchers to gather precise data that complements other observational techniques, helping us better understand the solar system's dynamics and the characteristics of various astronomical bodies. It has been particularly useful in tracking near-Earth objects and planning space missions.
