A pole star is a visible star, an especially prominent one, that is approximately aligned with the Earth's axis of rotation; that is, a star whose apparent position is close to one of the celestial poles, and which lies approximately directly overhead when viewed from the Earth's North Pole or South Pole. A similar concept also applies to other planets. In practice, the term Pole Star usually refers to Polaris, which is the current northern pole star, also known as the North Star.
The south celestial pole currently lacks a bright star like Polaris to mark its position. At present, the naked-eye star nearest to this imaginary point is the faint Sigma Octantis, which is sometimes known as the South Star.
While other stars' apparent positions in the sky change throughout the night, as they appear to rotate around the celestial poles, pole stars' apparent positions remain virtually fixed. This makes them especially useful in celestial navigation: they are a dependable indicator of the direction toward the respective geographic pole although not exact; they are virtully fixed, and their angle of elevation can also be used to determine latitude.

Volvo V60 Polestar Review
I'm losing my direction Something's come between us It's gettin' hard to do right I'm searchin' for a sign They've split us into sections I'm from Mars and your from Venus But stranded in the daylight Nothin' is defined But as the late summer honey light Shifts and caresses the buildings...
Dark starry eyes Searching the skies Because it's hidden from view Don't mean it isn't for you You know we're gonna make it We've only gotta take it Cos' it's a dark, dark sky Holds the North Star high And guides us and bathes us In stillness and sameness and blue
I've made a big decision In the light of the eternal I'm gonna be your mirror And you can mirror me I'll see you in the bright star Cushioned by the dark sky Reflected in the river Flowing to the sea And as the reasons and rumours recede Dyin' on the lesseing breeze
Sweet starry eyes Immune to surprise Because it's hidden from view Don't mean it isn't for you You know we're gonna make it We've only gotta take it And it's a dark, dark sky Holds the North Star high And guides us and bathes us In stillness and sameness and blue
And blue is the colour of my heart Since you blew my senses apart The feeling we're back at the start never ends As clusters of heavenly jewels Gaze down on Earth's lonely fools Turnin' and twistin' Resisting the pull of a fate that's already planned They can't understand
