1 Tranurethral resection of the prostate (TURP) is the most commonly used surgical treatment for BPH. 2  A small instrument is inserted through your urethra into the prostate. 3  The prostate is then removed piece by piece. 4  This procedure usually requires a hospital stay.
Next is precession, or wobble. This cycle occurs every 26,000 years. This gyroscopic wobble of the earths axis is driven by tidal forces which are influenced by our sun and moon. The Earth is actually not perfectly round so the gravitational pull tugs the axis over time creating the wobble cycle. Now there's a technical term for you.
Since obliquity is the angle between the axis of rotation and the direction perpendicular to the orbital plane, it changes as the orbital plane changes due to the influence of other planets. But the axis of rotation can also move (axial precession), due to torque exerted by the sun on a planet's equatorial bulge. Like Earth, all of the rocky planets show axial precession. If the precession rate were very fast the obliquity would actually remain fairly constant even as the orbital plane changes.
