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 estimate provided by NASA's Voyager 2 spacecraft nearly 40 years ago.

If you've been wondering how long the day on Uranus is, you probably need to get out more. But if you have, you'll be interested to know that observations by the Hubble Space Telescope have shown that it's 28 seconds longer than previously thought.

An analysis of 11 years of Hubble Space Telescope observations shows that Uranus ' day lasts 17 hours, 14 minutes, and 52 seconds. That's 28 seconds longer than NASA's Voyager 2 spacecraft estimated when it passed Uranus in 1986. Researchers reported the updated estimate April 7 in the journal Nature Astronomy.
