none of uranus's moons would appear as large as a full moon on earth from the surface of uranus, but the large number of them would present an interesting sight for observers hovering above the cloud tops. unlike on jupiter and saturn, many of the inner moons can be seen as disks rather than star-like points; the moons portia and juliet can appear around the size of miranda at times, and a number of other inner moons appear larger than oberon. the outer irregular moons would not be visible to the naked eye.
