alb5566741 Most of the nine major rings of Uranus can be seen in this back-lit painting of Uranus. At far right the distant sun can be seen, dimmed by its distance of over 19 times as far away as when seen from Earth. The object at lower center is very likely U15-Puck, one of the many minor inner satellites lying between the rings and the major moons of Uranus. With a diameter of 150 km and radius of 70 km this minor moon is probably composed of dirt and ice and has a very low albedo, or reflectivity. The rings of Uranus, aligned with the equator, shows how the planet is tipped over 90 degrees, which makes it unique within our solar system and causes the north and south poles to alternately point toward the sun during the planets' 84-year period of completing a single orbit around the sun.
