How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? This video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison.
In the time-lapse video, a day on Earth (one Earth rotation) takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest, but backwards. The inner rocky planets across the top underwent dramatic spin-altering collisions during the early days of the Solar System.
Why planets spin and tilt as they do remains a topic of research with much insight gained from modern computer modeling and the recent discovery and analysis of hundreds of exoplanets: planets orbiting other stars.
