The Great Orion Nebula (M42) is a diffuse nebula situated in the Milky Way, just below Orion's Belt. It is one of the brightest nebulae in the night sky, and, with good seeing, is visible to the naked eye. M42 is 1,344 light years away, and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass about 2000 times that of the Sun.
