Asteroid rotation is the study of the spin and rotation properties of asteroids in our solar system. Researchers study the rotational periods, obliquities, and shape of asteroids to better understand their physical properties, internal structures, and evolution. Observations of asteroid rotation are often conducted using ground-based telescopes, spacecraft missions, and radar imaging techniques to track the movement and orientation of these celestial bodies. Understanding the rotation of asteroids can provide valuable insights into their formation, composition, and potential hazards they may pose to Earth.
