Cancer

Cancer (The Crab) is the faintest constellation in the Zodiac with only 4 fourth magnitude stars. The two named below are Asellus Borealis, a spectral type A star more massive than our sun, lying about 181 light years away, and Asellus Australis, a spectral type K star lying about 131 light years away. But Cancer hosts a wonderful open star cluster, M44, called the Beehive because it reveals a multitude of faint stars in binoculars and in a small telescope. And for those with a moderate instrument, M67, another open cluster can be found in this part of the sky.
