The Trapezium or Orion Trapezium Cluster, also known by its Bayer designation of Theta1 Orionis, is a tight open cluster of stars in the heart of the Orion Nebula, in the constellation of Orion.

Telescopes of amateur astronomers from about 5 inch (127 mm) aperture can resolve six stars under good seeing conditions.[5].

It was discovered by Galileo Galilei. [1][2][3] The fourth component (B) was identified by several observers in 1673, and several more components were discovered later, for a total of eight by 1888. Trapezium Cluster, also known as the Orion Trapezium cluster is a tight group of stars in the constellation of Orion and the center of the Orion Nebula.Galileo is credited with its discovery when he sketched the stars in 1617 although he did not notice the nebulosity. globular cluster, open cluster, stellar association. The orbiting observatory's near-infrared camera revealed about 50 of these objects throughout the Orion Nebula's Trapezium cluster about 1,500 light-years from Earth.

It is most readily identifiable by the asterism of four relatively bright stars. In addition, brown dwarfs and low-mass runaway stars have been identified.

On February 4, 1617 he sketched three of the stars (A, C, D), but missed the surrounding nebulosity. Infrared images of the Trapezium are better able to penetrate the surrounding clouds of dust, and have located many more stellar components. Subsequently, several of the stars were determined to be binaries. Both A and B have been identified as eclipsing binaries. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. This view also doesn't show the assemblage of infant stars seen in the near-infrared image.
