  Jupiter has 95 known natural satellites, and it is likely that this number would go up in the future due to improved instrumentation. Of these, 79 are less than 10 km in diameter. The four largest moons are Ganymede, Callisto, Io, and Europa (in order of decreasing size), collectively known as the " Galilean moons ", and are visible from Earth with binoculars on a clear night.
