      A day on Uranus is 17 hours and 14 minutes in Earth-time. This means a day is shorter than here on Earth as Uranus spins faster than our own planet!

      Interestingly, a year on Uranus is 84 Earth-years! This is as it is so much further from the Sun than we are on Earth that it takes much longer (84 times longer!) to go around it… So you’d only have a birthday every 84 Earth-years if you lived on Uranus. That would not be fun!!
