Well, let's see . . . Each [supercluster] is made of several [clusters of galaxies]. Each [cluster of galaxies] is made of several [galaxies]. Each [galaxy] is made of seve
…ral [stars] ... maybe as many as several hundred billion of them in some galaxies. The galaxy that WE live in is estimated to consist of somewhere between 200 - 400 billion stars. The [sun] is one of them. So it looks like the sun is probably a little smaller than a supercluster. ====== Here's another way to put a sharp point on it: A beam of light takes about [4.6 seconds] to travel a distance equal to the diameter of the sun. A beam of light takes about [4.4 YEARS] to travel from here to the NEAREST star, out of the 200 - 400 billion stars in our galaxy, out of the several galaxies in our cluster, out of the several clusters in our supercluster. So the distances involved in galaxies are obviously more longer than the size of the sun. ( Full Answer )
