WebParallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines. [1] [2] Due to foreshortening, nearby objects show a larger parallax than farther objects, so parallax can be used to determine distances. WebIt can be applied to any kind of star where (a) you have a reasonable chance of determining the type of star from its spectrum and (b) where there is a single valued relationship …
