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 ...

A fresh analysis of a decade's worth of Hubble Space Telescope observations shows Uranus takes 17 hours, 14 minutes and 52 seconds to complete a full rotation — 28 seconds longer than the ...

The upshot is that we now know that a day on Uranus takes 17 hours, 14 minutes, and 52 seconds, or 28 seconds longer than the best previous estimate made by NASA’s Voyager 2 during its 1986 flyby.

What’s known about Uranus could be off the mark. An unusual cosmic occurrence during the Voyager 2 spacecraft’s 1986 flyby might have skewed how scientists characterized the ice giant, new ...

Neptune- and Uranus-type exoplanets are more abundant than Jupiter-like planets, and worlds called mini-Neptunes, with masses between that of Earth and Neptune, are even more abundant than those.

In 1986, NASA’s Voyager 2 made history as the first—and so far, the only—spacecraft to visit Uranus. This close encounter gave scientists a rare look at the planet’s magnetic field ...

In January 1986, Voyager 2 became the first — and so far the only — spacecraft to explore Uranus, and with its data, astronomers pegged the ice giant's rotation period at 17 hours, 14 minutes ...
