Answer:
The planet that has the greatest angle between its axis of rotation and the normal to the plane of its orbit is Uranus.
Step-by-step explanation:
Most planets are tilted in their orbit but Uranus has the greatest axial tilt of 98 degrees essentially meaning it is spinning on its side. Axial tilt is angle between rotational axis and orbital axis.
The large axial tilt causes the planet's the North Pole to be next to the equator and Astronomers believe that this tilt was caused by a collision with material that may be the size of the earth. The collision which may have occurred once knocked Uranus off of its normal orbital place.
