2. Stellar kinematicsStellar kinematics is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful information about the origin and age of a star, as well as the structure and evolution of the surrounding galaxy. In astronomy, it is widely accepted that most stars are born within molecular clouds known as stellar nurseries.
