Uranus’s Principal Satellites This “family portrait” (a montage of five Voyager 2 images) shows Uranus’s five largest moons to the same scale and correctly displays their respective reflectivities. (The darkest satellite, Umbriel, is actually more reflective than Earth’s Moon.) All five satellites have grayish surfaces, with only slight variations in color.
