The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses.[3] The total mass of the Omega Nebula is an estimated 800 solar masses.[4]

It is considered one of the brightest and most massive star-forming regions of our galaxy.[3] Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.[5]
