Well.. maybe we turned 90 degrees then
If you were to sight in on a few select stars, measure their location and compare the change over
time it will reveal the motions of the Earth. Any change in Earth's tilt will be apparent as well as any change in the tilt of our solar system.
People have been navigating by using the stars for thousands of years and no such change has ever been recorded. What has been recorded is that no
change has occurred that is outside of the normal motions that we are already aware of.
Saturn's axial tilt is 26.73° and Earth's is around 23.4°. Saturn takes just under 30 years to make one orbit around the Sun so in 15 years time
we get to see the extreme of Saturn's axial tilt. What that means is that from our perspective Saturn's axial tilt to the ecliptic will change by
53.46° (that's its axial tilt x2) over a 15 year period. Add our tilt of 23.4° and you get a tilt of 76.86° to Earth's equator, or apparent tilt
from our perspective.
The illustration you're showing is one I made some time ago that describes the perspective from our solar plane of the ecliptic to that of the
It shows that we are tilting by around 60° to the galactic plane and if you add the Earth's axial tilt (23.4°) you get an apparent tilt of almost
90°. This illustration further shows that actually if we were to follow the right hand rule we are titled by 120° to the galactic plane but that is
another matter. However, if the apparent tilt that we see in the Milky Way is moving it is doing so at a very slow rate. I don't think it has been
observed to change in recorded history but maybe someone else can show otherwise.
