what are the two types of motion that stars exhibit?
○ waning motion and waxing motion
○ intrinsic motion and extrinsic motion
○ apparent motion and actual motion
○ gibbous motion and geocentric motion
Apparent motion is the motion of stars as seen from Earth due to Earth's rotation and revolution. Actual motion refers to the real - world movement of stars through space, such as their orbital motion within a galaxy. Waning and waxing are terms related to the phases of the Moon. Intrinsic and extrinsic are not standard terms for star motion in this context. Gibbous is a Moon - phase term and geocentric is a model of the universe (not a type of star motion).
