Parallax is an angle subtended by two lines crossing a point. In the upper diagram, the Earth (blue-filled circle) in its orbit sweeps the parallax angle subtended on the Sun (yellow-filled circle). The lower diagram shows the equal angle swept by the Sun in a geostatic model.

The 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.

2024年4月30日 · Parallax is the apparent shift in the position of an object when observed from different viewpoints. This effect occurs because the perspective from which an object is viewed changes and makes it appear differently against a distant background.

Parallax 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.
