Uranus has an extreme axial tilt of 82 degrees, caused by a collision with an Earth-sized protoplanet 3-4 billion years ago, which makes it roll on its side rather than rotate upright; this results in each pole receiving 42 years of continuous sunlight followed by 42 years of darkness, yet the equator remains hotter than the poles—a mystery scientists have not yet explained; researchers measured Uranus's interior spin at 17 hours, 14 minutes, and 52 seconds by tracing auroral motion.
