How many bodies are there in the Solar System? There is the Sun, of course, and eight planets, and there are the smaller bodies: some dwarf planets, comets mostly in the outer reaches (some of them as big as dwarf planets), asteroids, and other debris and dust. The dust is spread out well enough, but there is an awful lot of space and a lot of dust. There are electrons, protons, and ions, but there would be no point in even starting to count them. Numbers don’t go that far. And there are moons, which do not have independent orbits around the Sun but travel with larger bodies.
