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.
Main article: Axial precession. Axial precession is the movement of the rotational axis of an astronomical body, whereby the axis slowly traces out a cone. In the case of Earth, this type of precession is also known as the precession of the equinoxes, lunisolar precession, or precession of the equator.
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.
