Obliquity of the Eight Planets. This illustration shows the obliquity of the eight planets. Obliquity is the angle between a planets equatorial plane and its orbital plane. By International Astronomical Union (IAU) convention, a planets north pole lies above the ecliptic plane. By this convention, Venus, Uranus, and Pluto have a retrograde rotation, or a rotation that is in the opposite direction from the other planets. The following table lists the obliquity and rotation period of each of the planets.
