PPT-Measuring Parallax

Parallax is the apparent displacement of an object against the background when seen from two different perspectives Definition of Parallax To measure the distance to a star astronomers measure the parallax shift of the star using 2 points of view that are as far apart as possibleat opposite sides of Earths orbit.
