Just to the north of Aries lies the small constellation of Triangulum. As its name suggests, it is a small triangle-shaped constellation formed by three not-so-bright stars.
All the three stars are of the fourth magnitude and can be seen only when the sky is dark and clear. Just to the west of the triangle can be seen a galaxy, M33. Although it is the brightest galaxy in the sky after the famous Andromeda galaxy (see p. 88), M33 is not visible to the unaided eye. But it can be seen with a pair of good binoculars or a moderate-power telescope, particularly on a clear moonless night.
