So I was on Wikipedia and saw that for Jupiter’s moons they used Mm for the distance or something from Jupiter. I’m confused does anyone know what Mm means?

mm is an abbreviation for millimeter. Space distances are measured in mega parsec or in millions of light years.In our solar system distance is measured in AU =astronomical units. It would be not convenient to measure it in milllimeters.
