the.com/celestial pole
Where the sky appears to stop spinning, because you're staring straight down Earth's axis.
means Either of the two fixed points in the sky — directly above Earth's North and South Poles — around which all the stars appear to wheel over the course of a night.
from From Latin caelestis, 'of the sky,' itself from caelum, 'heaven, sky' — and polus, Latin's borrowing of Greek polos, meaning the pivot or axis on which something turns, originally the axle-point of a spindle or sphere. Ancient skywatchers noticed that one point in the northern sky never moved while everything else circled it, and named it for exactly what it looked like: the axle-pin of the heavens.
