Getting a few things straight about our famous guiding star.
The presence of the North Star in our skies is familiar to most people living in the Northern Hemisphere. It sits above the true North Pole, never-moving while the other stars circle round it in a stately carousel. It is the brightest star in the sky, the one that has forever and will always point northwards…
So, who spotted the deliberate errors in the opening paragraph? There’s quite a few. Surprisingly, though, many people do believe them to be true. This is perhaps a symptom of our disconnectedness with the glories of the night sky in our light-polluted world. We no longer rely on the North Star and its companions to guide us on our way across oceans and continents – we have satellites and sat-navs for that. Nonetheless, let’s put a few of those myths to rest.
How to find the North Star
Polaris is in the constellation Ursa Minor (The Little Bear), but you can locate it best by first finding the easily recognisable, saucepan-shaped Ursa Major (The Great Bear or Plough, or Big Dipper in the USA). Take the two stars at the side of the ‘saucepan’ furthest from the ‘handle’, and draw a line from them until you reach Polaris (see diagram).
Where can I go to try this out?
Anywhere with reasonably low levels of light pollution. There are several good places to stargaze on Cranborne Chase AONB.
Is there a Southern Pole Star?
No – it’s pure chance that we have a star aligned with the Earth’s axis at the North Pole.
