Question

What is unique about the rotation of Uranus, and what caused it?

Answer 1

Sample Response: The axis of Uranus is tilted so that it appears to be rotating on its side. This may have been caused by a collision with a planet-sized body, which dramatically changed Uranus's rotation.

Answer 2

Uranus rotates on its side. Its axial tilt is 97.8 degrees, which is 74.3 degrees more than Earth. Scientists suspect that it may have been caused by a collision or series of collisions, although they believe it is probably more complicated than that.
