Taurus (constellation) of just 5.6 arc minutes, making them a challenge to split with the naked eye. This constellation includes part of the Taurus-Auriga complex, or Taurus dark clouds, a star-forming region containing sparse, filamentary clouds of gas and dust. This spans a diameter of and contains 35,000 solar masses of material, which is both larger and less massive than the Orion Nebula. At a distance of , this is one of the nearest active star forming regions. Located in this region, about 10° to the northeast of Aldebaran, is an asterism NGC 1746 spanning a width of 45 arcminutes.
