Question

Why objects which are far from us are seen to be small?​

Answer 1

Answer:

When they're further away, they take up less of your field of view, and so seem smaller. One way to measure our field of view is to use an angle. ... The further away the object is, the smaller this angle will be. So, the subject appears small, because it takes up less of your field of view.

Answer 2

$hello$

Answer:

The visual angle that determines apparent size can be thought of as the angle at the top of a triangle. ... As an object gets closer, the visual angle increases, so the object appears larger. As the object moves farther away, the visual angle decreases, making the object appear smaller.
