Is Uranus really tilted on its side? Yes, Uranus is really tilted on its side! Uranus has the largest tilt of any planet in our solar system and it spins on its side. This means that one of Uranus' poles is often pointed towards the sun giving Uranus very long seasons. The rings of Uranus are also sideways compared to the rings of other planets. Why Uranus has such a large tilt is still a mystery. Many astronomers think that Uranus may have been hit by something really big a long time ago, and was knocked over on its side.
