Along with hip and groin pain, you may experience joint stiffness, cracking or popping, and muscle loss or atrophy. Weight-bearing activities like walking may increase your symptoms and further degenerate your joint.
All stars rotate and are therefore flattened by the centrifugal force. The faster the rotation, the more oblate the star becomes. Our Sun rotates with a period of 27 days and has a radius at the equator that is 10 km larger than at the poles; for the Earth this difference is 21 km.
But, Uranus and Venus have retrograde rotation where the axial rotation is opposite to the orbital motion; that is they have a clockwise axial rotation and a counter-clockwise orbital motion. This means that for Venus at least, the Sun rises in the west and sets in the east. Uranus is a bit different still. Its axial tilt, which is the angle the rotational axis of a planet makes to its orbital plane, is 97.7 degree. This sideways tilt gives Uranus a unique position in which its axis of rotation is nearly in its orbital plane.
