However, it's important to note that comparing the "fit" of stars is tricky because they aren't perfectly spherical. They have atmospheres that are diffuse, and the exact size is difficult to determine.

That said, if we were to consider a rough volume comparison, the Pistol Star's volume would be 1 million times greater than our sun's volume. This means that roughly 1 million suns could fit inside the Pistol Star if we were able to ignore their densities and treat them as perfect spheres.
