A casting shadow is always bigger or at least equal size to it’s object. but never smaller.
And the size and sharpness depends on the distance between the light source and the object.
So how come the casting shadow of the moon during an eclipse on the earth's surface is only 70 miles wide?
While the moon itself has a diameter of 3,476.28 km!

The answer to that question is  one word.
