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 — that's 28 seconds longer than the ...

previous coordinate systems based on outdated rotation periods quickly became inaccurate, making it impossible to track Uranus’ magnetic poles over time,” lead author Laurent Lamy, from the ...

For astronomers, determining a planet’s interior rotation rate is challenging and scientists can’t take direct measurements of Uranus. To try and solve this, the team on this study developed a ...

Analysis of the Hubble imagery, combined with the data collected by Voyager 2, allowed for a more exact calculation of Uranus’ rotation speed. What they found did indeed fall within the original ...

Scientists reported Monday that observations by the Hubble Space Telescope have confirmed it takes Uranus 17 hours, 14 minutes and 52 seconds to complete a full rotation. That’s 28 seconds ...

This approach can now be used to determine the rotation rate of any celestial object with a magnetic field and auroras — including exoplanets. Uranus just got a little more time on its hands.

A day at Uranus just got a little longer. Scientists reported Monday that observations by the Hubble Space Telescope have confirmed it takes Uranus 17 hours, 14 minutes and 52 seconds to complete ...
