how long is a day on earth compared to space
A day on Venus is 243 Earth days. Venusâ day is actually longer than its year. It only takes 224.7 Earth days for the planet to orbit the Sun. We measure a day on Earth as a period of 24 hours, but it actually takes the planet 23 hours 56 minutes and 4 seconds to rotate on its axis.ome astronomers believe that we will never know how long a day on Saturn is. A day on Uranus only takes 17 hours 14 minutes and 24 seconds. Since the planet has such an extreme axial tilt (97.8Â°), it actually rotates on its side. A day on Neptune lasts 16 hours 6 minutes and 36 seconds in Earth time.
