This small northern constellation presents as well-formed triangle of three stars. It was one of the 48 constellations cataloged by 2nd century astronomer Ptolemy that remain among the 88 modern constellations. It is not bright enough to jump out at the observer, but can be seen in all but the most light-polluted skies. Look for it high overhead between Perseus, Andromeda, and Pisces in December. M33, the Triangulum Galaxy, is the brightest and most notable deep sky object in this constellation.
