👉 Platevindex is a method used in astronomy to estimate the distance between two celestial objects based on their apparent positions relative to each other. It involves measuring the angle between the observer's line of sight and the object's apparent position, using an instrument called a plate vanillin or a vanillin plate. The closer the angle between the object and the observer is to zero degrees, the greater the distance between them. This method has been widely used in astronomy for determining distances between stars and galaxies.
