The Cosmos

oTo paraphrase William Blake, if we can see the earth as a grain of sand, then the sun is the size of an orange twenty feet away; Jupiter would be eighty-four feet in the other direction; Neptune and Pluto, larger and smaller grains, would be found at a distance of two and a quarter blocks away from the grain of sand called planet Earth.
