AI overview

Triangulum is a small constellation in the northern sky named after the triangle shape formed by its three brightest stars, and it has been recognized since ancient times, appearing in Ptolemy's 2nd century catalog of 48 constellations. The constellation's stars were formally catalogued by later astronomers Johann Bayer and John Flamsteed, who assigned Greek letter designations to six of them.
