Messier 33 (M33), triangular nebula, or triangular galaxy is a spiral galaxy with a diameter of approx. 60.000 Lj. and the total brightness of 5.7 mag in the constellation triangle. This makes it the second brightest spiral galaxy in the nightsky after the Andromedanel and one of the closest to us. However, its brightness is distributed over a larger area, so that under normal conditions it is not visible to the naked eye, but only in the field as a weak foggy spot.
