Parallax space definition
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. Webparallax. ( ˈpærəˌlæks) n. 1. (General Physics) an apparent change in the position of an object resulting from a change in position of the observer. 2. (Astronomy) astronomy the angle subtended at a celestial body, esp a star, by the radius of the earth's orbit. Annual or heliocentric parallax is the apparent displacement of a nearby star ...
