1590s, "a constellation, a small grouping of movie stars," from Greek asterismos "a marking with performers," from aster "celebrity" (see astro-). Any grouping of movie stars, whether a constellation or perhaps not (though in contemporary usage, usually the second). The "huge Dipper" is an asterism, maybe not a constellation.

- (n.) An optical residential property of some crystals which show a star-shaped by reflected light, as star sapphire, or by transmitted light, as some mica.
The asterism seems due to the presence of microscopic tubular cavities, or to enclosure of crystalline minerals, arranged in a definite system.
