Excellent animation comparing the rotations of the planets in our solar system
James O’Donoghue, a planetary scientist at JAXA (Japan Aerospace Exploration Agency), made this excellent clip comparing the rotations, tilts, and sidereal day lengths of the eight planets and two of the dwarf planets in our solar system.
There are many more dwarf planet candidates, but they aren’t mapped so aren’t included," O’Donoghue writes. "More space missions would be a good idea."
Below, another one of O’Donoghue’s fantastic videos:
