Almost Every Object in the Solar System Has Its Own Exosphere, Right?

Almost certainly every object in the solar system has an exosphere because they're not just alone, right? They're all in the solar wind. So we think that for example, Enceladus and Europa and Callisto and Ganymede and even dwarf planets like Ceres in the asteroid belt probably have their own little exosphere of their own. It's incredible that we can collect enough data from these very thin exospheres to learn this kind of stuff.
