A day on Uranus is 28 seconds longer than estimated: Research
A day on Uranus is 28 seconds longer than earlier estimates, researchers reported after analysing 11 years of Hubble Space Telescope observations. A day at Uranus lasts 17 hours, 14 minutes, and 52 seconds, which is 28 seconds more than what NASA's Voyager 2 spacecraft estimated. "The continuous observations from Hubble were crucial," one of the researchers said.
