Small angle formula 206265
Did you know?
WebbThe number 206,265 is approximately equal to the number of arcseconds in a circle (1,296,000), divided by 2π. The exact formula is D = d tan ( X ·2π/1,296,000) and the above approximation follows when tan ( X) is replaced by X .

This makes sense when we further think about it. Celestial objects are so fr away and so small, it is better to … byschipmateIn astronomy, the angular size or angle subtended by the image of a distant object is often only a few arcseconds, so it is well suited to the small angle approximation. The linear size (D) is related to the angular size (X) and the distance from the observer (d) by the simple formula: where X is measured in arcseconds.
