Cancer (The crab)

CancerCC_croppedCancer, the crab, is a zodiacal constellation of rather dim stars that can be difficult to see in light polluted skies. It is one of the 48 constellations cataloged by 2nd century astronomer Ptolemy. Cancer is located on the ecliptic, half way between Pollux in Gemini and Regulus in Leo, and is highest in the sky at nightfall in March. If Cancer’s stars are not visible, try using binoculars, and then look again once the various stars in the constellation have been located. Cancer is home to two Messier objects, M44 (the Beehive Cluster, or Praesepe) and M67.
