In this hands-on activity, students explore the relationship between angular width, actual size, and distance by using their finger, thumb and fist as a unit of angular measurement. They should learn to relate angular width to actual size using distance; quantify the relationship between angular width and distance; and understand why the Sun appears smaller from Pluto than from Earth.
