What is the difference between a shadow of an object created by a small light source and the sun?

Shadow from light source always bigger than object but shadow from the sun is the same size as object.

Great different is due to the distance of light source.

Size of shadow is double at distance x 2 source to object. Shadow is always bigger than object.

You will notice your shadow is bigger in light bulb or stadium spot light but the shadow from sun is the same size as object. This is due to great distance from sun to us (150 million km approximately) the double distance to see our shadow to be double is at 300 million km from the Sun. at merely 10 m or 100 km is almost no distinguishable different in shadow size to the object. We then presume shadow cause from sunlight is equal to the size of the object.
