Parallax - Wikipedia
WEBTo measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term parallax is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit.
Parallax Definition & Meaning - Merriam-Webster
WEBThe meaning of PARALLAX is the apparent displacement or the difference in apparent direction of an object as seen from two different points not on a straight line with the object; especially : the angular difference in direction of a celestial body as measured from two points on the earth's orbit.
What Is Parallax? - ScienceAlert
WEBParallax is the change in an object's relative position as seen from two different positions. Mathematically speaking, the relationship between any two observation points and a distant object can be summed up in what's known as a parallax angle.
