Top 5 Absurd Space Myths

Brightest Star


The Myth: Polaris is the brightest star in the northern hemisphere night sky
 
Sirius is actually brighter with a magnitude of 1.47 compared to Polaris’ 1.97 (the lower the number the brighter the star).
The importance of Polaris is that its position in the sky marks North – and for that reason it is also called the “North Star”.
Polaris is the brightest star in the constellation Ursa Minor and, interestingly, is only the current North Star as pole stars change over time because stars exhibit a slow continuous drift with respect to the Earth’s axis.
