Uranus and Moons

Read News Release View All Press Releases

Four small, white dots appear widely spaced in a steep, roughly jagged, diagonal line from top right to bottom left. These white dots appear against a solid black background. A fifth small, white dot is superimposed on a much larger blue sphere, which is also on the black background. This medium-blue sphere has pink, white, and lighter blue diagonal striations. Also superimposed on this striated sphere is a tiny black dot, which is just to the right and slightly beneath the white dot. Encircling the blue sphere at the same steep diagonal angle as the white dots and striations are thin, ghostly, white, Saturn-like rings. The four white dots are labeled, from top right to bottom left, “Titania,” “Oberon,” “Umbriel,” and “Miranda.” The white dot and its accompanying black dot, which are both superimposed on the blue sphere, are labeled “Ariel and shadow.” The faint, Saturn-like rings encircling the blue sphere are labeled simply “rings.”

Caption

The five largest moons of Uranus – sometimes called the “classical moons” -- appear in a jagged, roughly diagonal line from top right to bottom left. These are labeled Titania, Oberon, Umbriel, Miranda and Ariel. Also visible is Ariel’s shadow, which is superimposed on Uranus. Faint, ghostly, Saturn-like rings encircle the blue ice giant.
