How much wider is the Carina Nebula in physical dimensions compared to the Orion Nebula?

Answer

Nearly twelve times wider

The sheer physical dimensions of the Carina Nebula are vast, spanning approximately 300 light-years across. In contrast, the Orion Nebula, a famous star-forming region, measures only about 24 light-years in width. Performing the direct comparison shows that the Carina Nebula is nearly twelve times wider than the Orion Nebula. This massive size difference highlights the colossal scale of the Carina complex as a stellar nursery within the Milky Way, illustrating that the apparent density seen in images can be deceiving regarding the true separation of material across its immense volume.
