hmmm, about the size of an asprin tablet or pea at arm's length, seems to agree with somewhat smaller than thumbnail [1]. maybe i should find and measure some sand now :). in either case, 1/10 the width of the moon is so much easier to comprehend. when is the last time anyone tried holding a grain of sand at arms length? what a weird comparison to make when everyone on earth already has a stable/familiar reference in the sky.
