| Cancer (The Crab) |
|
A zodiacal constellation, among those listed by Ptolemy (c. AD 140). It is said to represent the crab crushed under the foot of Hercules when he was fighting the Hydra. None of the stars is brighter than fourth magnitude, though the star cluster Praesepe at the constellation's centre can be seen with the unaided eye. See also: Table 4. |
