Stars have been seen in the sky as long as humans can remember. Constellations are just patterns of stars as we see them. Cancer is such a pattern. So the very first time a human being looked at the night sky was the very first time it was seen. Over time people began to name constellations. There are now 88 such constellations, which cover all the stars we see. Over the centuries some stars have changed from one to another by people re-designating them. The stars in constellations usually have no real connection to each other, but just happen to seem to be beside each other, when in fact they are huge distances from each other.
