These are the largest moons in our solar system (in terms of surface area) according to universeguide.com as of 5/28/2020 A.D. This is the link to my source:https://www.universeguide.com/blogarticle/what-are-the-largest-moons-in-the-solar-system
Apologies, the source I used did not mention Mimas. Upon further inspection however, a separate article said that Mimas had a larger diameter. The quiz will be fixed.
