The radio occultation of Voyager 2 by the rings of Uranus on January 24, 1986 provided the first observations of this system at microwave wavelengths ( λ = 3.6 and 13 cm). Fine resolution (50 and 200 m) optical depth profiles at λ = 3.6 cm depicting the nine pre-Voyager rings, ...
First, a bit of background: Uranus has only been visited by a spacecraft once, when NASA'sVoyager 2zipped past the planet in 1986. The flyby produced many beautiful and iconic views of the almost featureless, light-blue world. Astronomers have made countless ground-based observations of Uran...
Uranus on 1986-01-23, taken by NASA's Voyager 2 probe. This color image was composed of three frames, orange, green, and blue, taken by Voyager 2's imaging system. This color image has been calibrated to best represent Uranus's true color and appearance. Based on: Irwin, Patrick G ...
A brief examination of historical observations is given which includes its discovery, position determination, and the related discoveries of Uranus' five large satellites and rings. The observational data preceding the Voyager 2 mission are reviewed in terms of the planetary interior, atmosphere, and ...

Deep within Neptune and Uranus,it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain ha...
Uranus - Gas Giant, Rings, Moons: At Uranus’s distance from the Sun, the planet takes slightly more than 84 Earth years, essentially an entire human life span, to complete one orbit. The eccentricity of its orbit is low—that is, its orbit deviates litt
NASA'sVoyager 2was the first and as yet, only spacecraft to visit Uranus. Although there isn't a spacecraft on its way to Uranus at the moment, astronomers regularly check in with the planet using the Hubble and Keck telescopes.
Uranus as seen from Voyager 2 Uranus Facts: Uranus's rings look white in pictures, but they are really made of asphalt-colored material. When it was first discovered, Uranus was mistaken for a star. It was named "34 Tauri". Uranus rotates on its side like Pluto. ...
