The celestial space of a constellation is marked like a pole-to-pole segment of a peeled orange. It is a geometrical division of the star world. A galaxy group is bonded, about its center.

Explanation:

Starting with 12 zodiacs for #(12 X 30) 360^o# around earlier,
( https://en.wikipedia.org/wiki/Zodiac ), they are now regrouped, with more and more new-find stars, into 88 astutely marked constellations.
See https://starchild.gsfc.nasa.gov/docs/StarChild/questions/88constellations.html.
Even now, astrologers use baby's birth-time star, and the zodiac to which it belongs, for predictions about the child's life.

Galaxy is a gravitational system, of star systems, held together about its Black Hole center(s) and well separated from neighboring galaxies. Milky Way and Andromeda are examples.
