ASTROKINETIC MOTIONS Meaning and
Definition
-
Astrokinetic motions, also known as astrometric motions, refer to the apparent movements of celestial objects across the sky. Derived from the Greek words "astron" (star) and "kinetikos" (movable), astrokinetic motions involve the apparent change in position of celestial bodies as perceived from Earth.
The earth's rotation on its axis causes the sky to appear to move, resulting in the apparent motion of celestial objects. Astrokinetic motions are typically expressed in terms of the angular displacement or change in position of celestial bodies over a unit of time, such as arcseconds per year or degrees per hour.
These motions can be observed and measured using astrometry, a branch of astronomy that focuses on the precise measurement and study of the positions and motions of celestial objects. Astrometric observations provide invaluable data for various areas of astronomical research, including the determination of stellar distances, the detection of exoplanets, and the study of the structure and dynamics of our galaxy.
Astrokinetic motions can be affected by various factors, including the gravitational influence of other celestial objects, such as planets or nearby stars, and the influence of the Sun and Moon. Accurate measurements of these motions are crucial for determining the proper motion, parallax, and other important properties of celestial objects, enabling astronomers to unravel the mysteries of the Universe and advance our understanding of its vastness and complexity.
