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 ...

Voyager 2 flew by Uranus in 1986, giving us our only up-close look at the planet – but unusual space weather just before the craft arrived has given us a misleading idea about the planet’s ...

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.

The complicated magnetic environment of 'weird' Uranus. The four moons in this study—Ariel, Umbriel, Titania, and Oberon—are tidally locked to Uranus, so that they always show the same side to ...

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 ...
