Polaris at 42°
~42°
Measured
Altitude of Polaris as seen from geographic latitude ~42° N
The north celestial pole’s altitude is the observer’s latitude. Polaris is currently ~0.5° off the pole. At 42° N you see it near 42°.
What it supports
A coordinate tautology, printed honestly. The Book’s Polaris plate is a looking-lesson, not a miracle.
What it does not
Not a special property of Polaris. Not evidence that 42° is written on the sky independent of the observer.
