Hercules (constellation)
Named after the
Roman version of the
Greek mythological hero
Heracles,
Hercules is the fifth largest of the 88 modern
constellations. It was also one of
Ptolemy's 48 constellations. It has no
first magnitude stars, but contains two of the most conspicuous globular clusters:
M13, the brightest
globular cluster in the northern hemisphere, and M92.
