north star, n.All

The North Star has not always been our guiding light and it won't always be in the future. In 11,000 years, Vega will take its place, and in another 13,000 years after that, Polaris will once again be Earth's North Star

The North star is the best of road maps; simple, clear, and you don't have to refold it

The North star has a true-fixed and resting quality for which there is no fellow in the firmament.
