Solar Polar Alignment

Postby BDanielMayfield » Mon Mar 20, 2017 2:36 pm

As most know, the Earth's North Pole is roughly aligned with Polaris, the North Star, located near 90 degrees north on the celestial sphere. Where though are the Sun's polar points located? Edit: To what points on the sky do the Sun's poles point?

The Sun, which is curiously tilted with respect to the ecliptic, has its north pole at 286.1°+63.9°, placing it in Draco, a few degrees from delta Dra (Altais). The Sun's south pole is at 106.1° -63.9°.

Thanks. I couldn't find these points myself. I did find that the Sun's obliquely to the ecliptic is 7.25 degrees, which I surmise is the angle between due north or south to those points.

It is curious that the Sun's rotation is tilted by 7.25 degrees to the plane of the ecliptic, since everything in the solar system was formed from the same collapsing cloud of gas and dust. (Please don't think that I doubt this for any reason, because I don't.)

Its tilt is closer to 6° from the invariable plane, which is mostly determined by Jupiter, and is therefore very close to Jupiter's orbital plane. There has been some work over the last year or two arguing why this might be.

So, another clue to the existence of the elusive Planet X, err, 9? Cool.

Jupiter's tilted reign on the invariable plane Planet Nine might explain :?:
