Quizplus · Accepted Answer

An angle of 1 arcsecond is incredibly small, measuring at approximately 1/3600th of one degree. It is much smaller than the width of a human finger or fist held at arm's length and even smaller than the thickness of a human hair held at arm's length. The width of a basketball held at arm's length is much larger than 1 arcsecond.
