Proper motion COSMOS - Swinburne

WebIn astronomy, the term proper motion refers to the angular velocity across the sky exhibited by a celestial body. The enormous distances to the stars means that only the closest have proper motions that are large enough to be expressed in arcseconds per year – milliarcseconds per year are more common. Because of these small angular velocities, it … WebIn this application of the small angle equation, the angular size (a) becomes the parallax angle ( ρ ) and the linear size (d) is the Earth-Sun distance.
