[[File:Orion Nebula.png|thumb|220x220px|ORION NEBULA]]The '''Orion Nebula''' (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way. It is one of the brightest nebulae and is visible to the naked eye in the night sky. The M42 nebula is estimated to be 24 LYs across. It is one of the most scrutinized and photographed objects in the night sky and is among the most intensely studied celestial features. The '''Orion Nebula''' contains a very young open cluster, known as the '''Trapezium''' due to the asterism (any pattern of stars recognized in the Earth's night sky) of its primary four stars.

There are ~~eight~~ star clusters associated with the nebulae in the Orion region:

There are seven star clusters associated with the nebulae in the Orion region:

'''NGC 2232''' can be found by navigating to '''10 Monocerotis'''.

~~Also,~~ near the ~~Orion~~ Nebula ~~region~~, in the ~~southern hemisphere is the~~ carbon star '''R Leporis'''~~. Sometimes~~ called Hind's Crimson Star, ~~'''R Leporis'''~~ is a well-known variable star in the constellation Lepus, near its border with Eridanus. '''R Leporis''' can be found by navigating to '''R Leporis'''.

==== '''Objects near the Nebula''' ====

'''IC 418 '''(also known as the '''Spirograph Nebula'''), is a planetary nebula in the Milky Way Galaxy. It can be reached by navigating to '''BD-12 1172'''.

The carbon star '''R Leporis, s'''ometimes called Hind's Crimson Star, is a well-known variable star in the constellation Lepus, near its border with Eridanus. '''R Leporis''' can be found by navigating to '''R Leporis'''.

'''IC 2118''' (also known as the '''Witch Head Nebula''' due to its shape) is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in Orion. The Witch Head Nebula can be reached by navigating to the '''Witch Head Nebula'''.

The nebula '''Messier 78''' (also known as M 78 or NGC 2068) is a reflection nebula in the constellation Orion. It can be found by navigating to '''Messier 78'''.

The Running Man Nebula, Barnard's Loop, The Horsehead Nebula, the Flame Nebular, the Horsehead Dark Region, and the Orion Dark Region are also located within this region.
