TRIVIAL PURSUITS: Unique Fact about Uranus

What difference does Uranus have from all the other planets?
Most of the planets rotate on an axis that is more or less perpendicular to the plane of their respective orbits around the Sun. But Uranus’s axis lies almost parallel to its orbital plane, which means that the planet spins nearly on its side, its poles taking turns pointing toward the Sun as the planet travels in its orbit.
