... Constellations are star patterns on the sky ? ... Every star or galaxy we see can then be located on one of the 88 constellations into which we have divided the sky (coincidentally, the same number as there are keys on the piano.) Each of the 88 regions takes its name from the best-known star group or picture in that region, so the constellation Orion is the sector of the sky that includes the easily recognized star-pattern of Orion the Hunter. ...
