|The '''Trapezium''' or Orion Trapezium Cluster, also known by its Bayer designation of Theta Orionis, is a tight open cluster of stars in the heart of the '''Orion Nebula''', in the constellation of Orion. It is a relatively young cluster that has formed directly out of the parent nebula and may be a sub-component of the larger '''Orion Nebula Cluster'''. | |||
This star cluster is most readily identifiable by the asterism of four relatively bright stars for which it is named. The four are often identified as A, B, C, and D in order of increasing right ascension. The brightest of the four stars is C, or Theta Orionis C. | |||
