Default The North pole and Equator of the Sun


When it was discovered that the planets orbit the Sun, it became an issue of speculation as to why they did so with particular emphasis on solar rotation imparting orbital motion on smaller objects -

"The Sun and the Earth rotate on their own axes...The purpose of this
motion is to confer motion on the planets located around them;on the
six primary planets in the case of the Sun,and on the moon in the case
of the Earth.On the other hand the moon does not rotate on the axis of
its own body,as its spots prove " Kepler

The Sun's Equatorial circumference defines the orbital plane for all planets so all planetary inclinations are referenced off that solar system feature where the Sun has a zero degree inclination. Lots to discuss here including the predominance of activity around mid latitudes of the Sun in contrast to lesser sunspot activity happen towards the Sun's polar regions where rotational speeds are less.

Rather than the usual all-singing-all-dancing miserable conclusions chanted about the Universe, there is room for genuine physics discussions about the rotation of the Sun and how that motion affects its surroundings or in the case of the planets, including ours, affects their surroundings and for the Earth specifically geological evolution, climate and so on.
