Space Motion

Space motion refers to the movement of celestial objects, like stars and planets, through space. It includes their trajectory, velocity, and changes in position over time. By measuring this motion, astronomers can understand how objects orbit within galaxies, interact gravitationally, or travel through the universe. Space motion is determined by observing changes in position relative to more distant background objects, often over years or decades. Understanding these movements helps us learn about the object's origin, age, and the gravitational influences acting upon them, providing insights into the dynamic nature of our universe.
