The Orion Molecular Cloud Complex (or, simply, the Orion Complex) is a large group of bright nebulae, dark clouds, and young stars in the Orion constellation. The cloud is between 1500 and 1600 light-years away, and hundreds of light-years across. Several parts of the nebula can be observed through binoculars and small telescopes, and some parts (such as the Orion Nebula) are visible to the naked eye.

The nebula is important because of its sheer size, as it spreads several degrees from Orion’s Belt to his sword. It is also one of the most active regions of stellar formation visible in the night sky, and is home to both protoplanetary discs and very young stars.
