This is a photo montage of Uranus and five of it’s largest moons. The photos were taken separately by the Voyager 2 spacecraft. The moons, from largest to smallest as they appear here, are Ariel, Miranda, Titania, Oberon and Umbriel.
When Voyager 2 visited the planet, it discovered 10 new smaller moons and took close-up pictures of its ring system.
