About

This simulation demonstrates the small-angle approximation, a useful formula in astronomy and physics for relating an object's linear size, its distance, and its angular size in the sky.

α (arcsec) = 206,265 × (diameter / distance)

The number 206,265 is the approximate number of arcseconds in one radian.
