The constellations have been known as long as people can remember. A constellation is just a pattern stars appear to make in the sky as we look at them, though most of the stars that we associate as being part of any constellation have no connection to each other. Various ancient peoples have given names to the various constellations and those names still exist today.
Aside from Cancer being the dimmest zodiacal constellation, the planet Mars is in Cancer (as of 4/21/10)
Cancer is most likely to be found in the spring time. Around mid April or May is the best time to view it. At 9:00 pm is when you will get the best view of this constellation.
The constellation of Cancer was not really "discovered or found" at any point in time but was passed on from ancient times through myth and folklore. It got the name we know today from the Greeks and is associated with the myth of Hercules. It is important to understand that the pattern of stars now known as the constellation Cancer, and any constellation for that matter, meant different things to different people throughout the ages.
