Question

Quizplus · Accepted Answer

Parallax is a method used to directly measure the distance to an object, by observing its apparent position from two different locations. It is based on the fact that objects that are closer to us will appear to shift position more compared to more distant objects when viewed from different locations. Parallax cannot be used to directly measure velocity, luminosity or mass.
