Names and Boundaries of Constellations
The sky was arbitrarily divided into constellations by historic astronomers, according to perceived patterns in the sky. At first, only the shapes of the patterns were defined, and the names and numbers of constellations varied from one star map to another. Despite being scientifically meaningless, they do provide useful reference points in the sky for human beings, including astronomers. In 1930, the boundaries of these constellations were fixed by Eugène Joseph Delporte and adopted by the IAU, so that now every point on the celestial sphere belongs to a particular constellation.

Famous quotes containing the words names and/or boundaries:
““Well then, it’s Granny speaking: ‘I dunnow!
Mebbe I’m wrong to take it as I do.
There ain’t no names quite like the old ones, though,
Nor never will be to my way of thinking.
One mustn’t bear too hard on the newcomers,
But there’s a dite too many of them for comfort....’””
—Robert Frost (1874–1963)
“Ideas are not thoughts; the thought respects the boundaries that the idea ignores thereby failing to realize itself.”
—Franz Grillparzer (1791–1872)
