The size of stellar nebulae can vary greatly. Some are relatively small, with diameters of only a few light-years, while others can be much larger, spanning hundreds or even thousands of light-years. For example, the Orion Nebula, one of the most famous and well-studied stellar nebulae, has a diameter of about 24 light-years. In contrast, the Tarantula Nebula, located in the Large Magellanic Cloud, is a much larger stellar nebula, with a diameter of about 1800 light-years.
