In Greek mythology, the hunter Orion was the most handsome of men. He was the son of the sea god Poseidon and Euryale, the daughter of King Minos of Crete.

Rigel – β Orionis
Rigel is the brightest star in the constellation. With an apparent magnitude of 0.18, it is also the sixth brightest star in the sky. Even though it does not have the designation alpha, it is almost always brighter than Betelgeuse, Alpha Orionis. Rigel is really a star system composed of three stars. It has been a known visual binary since 1831, possibly even earlier, when F. G. Struve first measured it. Rigel is surrounded by a shell of expelled gas. The name Rigel comes from the Arabic phra...
Betelgeuse – α Orionis
Betelgeuse is the second brightest star in Orion and the eighth brightest star in the sky. It is a red supergiant, belonging to the spectral class M2lab. The suffix -ab indicates that Betelgeuse is classified as an intermediate luminous supergiant, one not as bright as others such as Deneb in the constellation Cygnus. Some recent findings, however, suggest that the star emits more light than 100,000 Suns, which would in fact make it more luminous than most stars in its class, so the classific...
Bellatrix – γ Orionis
Bellatrix, sometimes also known as the Amazon Star, is the third brightest star in Orion and the 27th brightest star in the sky, only slightly dimmer than Castor in Gemini. Its name comes from the Latin word for “the female warrior.” It has a mean apparent magnitude of 1.64 and is approximately 240 light years distant. Bellatrix is a hot, luminous blue-white giant star, classified as an eruptive variable. Its magnitude varies between 1.59 and 1.64. The star belongs to the spectral class B2 II...
Orion Molecular Cloud Complex
The Orion Molecular Cloud Complex, or simply the Orion Complex, is comprised of a large group of dark clouds, bright emission and reflection nebulae, dark nebulae, H II regions (large clouds showing recent star forming activity) and young stars in the constellation Orion. The Orion Complex is between 1,500 and 1,600 light years distant. Several parts of it – the famous Orion Nebula, for one – can be seen without binoculars. The Orion Molecular Cloud Complex contains most of the well-known dee...
Orion Nebula – Messier 42
The Orion Nebula, or Messier 42, is a diffuse emission reflection nebula located south of the three stars that form Orion’s Belt. Sometimes it is also called the Great Nebula or the Great Orion Nebula. The nebula is one of the brightest ones in the sky and can be seen without binoculars. It has a visual magnitude of 4.0 and is 1,344 light years distant from Earth. To the unaided eye, the Orion Nebula appears as the slightly blurry central “star” in Orion’s Sword, south of Orion’s Belt. Messie...
Trapezium Cluster
The Trapezium Cluster is a young, tight open star cluster located in the centre of the Orion Nebula. It is 47 arc seconds in size and has an apparent magnitude of 4.0. The cluster was first discovered by Galileo Galilei on February 4, 1617. He drew three of the stars (A, C and D), and the fourth one was added by observers in 1673. By 1888, eight stars were discovered in the cluster. The brightest five emit most of the light that illuminates the surrounding nebula. The Trapezium Cluster is eas...
