Exploration of Uranus cloud tops. This was the probe's first solo planetary flyby, since "Voyager 1" ended its tour of the outer planets at Saturn's moon Titan. Uranus is the third-largest planet in the Solar System. It orbits the Sun at a distance of about and completes one orbit every 84 years. The length of a day on Uranus as measured by "Voyager 2" is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on its side. Its unusual position is thought to be the result of a collision with a planet-sized body early in the Solar
Climate of Uranus was imaged. In that year observations from both Hubble Space Telescope and Keck Telescope revealed a small dark spot in the northern (winter) hemisphere of Uranus. It was located at the latitude of about and measured approximately 2° (1300 km) in latitude and 5° (2700 km) in longitude. The feature called Uranus Dark Spot (UDS) moved in the prograde direction relative Uranus's rotation with an average speed of , which is almost faster than the speed of clouds at the same latitude. The latitude of UDS was approximately constant. The feature was variable in size and appearance and was often
