Isaac Newton, and others since his day, have shown that the Earth's precession is caused by the gravity of the Moon and Sun acting on the oblateness of the Earth. Since it can be calculated so accurately I have to believe it is true. The obliquity, or angle between the plane of the Earth's orbit and the axis, is about 23 degrees but varies between 22.1 and 24.5 degrees, in-phase with the precession circuit.
As on Earth, there is a second form of precession: the point of perihelion in Mars's orbit changes slowly, causing the anomalistic year to differ from the sidereal year. However, on Mars, this cycle is 43,000 years rather than 112,000 years as on Earth. On both Earth and Mars, these two precessions are in opposite directions, and therefore add, to make the precession cycle between the tropical and anomalistic years 21,000 years on Earth and 27,000 years on Mars.
