How long is a day on Uranus?
A planet's day is the time it takes the planet to rotate or spin once on its axis. Uranus rotates faster than Earth so a day on Uranus is shorter than a day on Earth. A day on Uranus is 17.24 Earth hours while a day on Earth is 23.934 hours. However, Uranus spins backwards compared to Earth and most of the other planets.
