All about the North Star

According to Space.com, "the North Star is a depicted as a triple star system." The North Star is really called Stellia Polaris. A known fact is that Polaris isn't the brightest star, but from what we can see it is. It is not the top 40; it is actually the 48th brightest star.

The North Star is actually important because the axis of the Earth is pointed directly towards it. The North Star doesn't really move; it stays above the northern while the other stars move around it.

Polaris is not going to always be the North Star. "Polaris is a Cepheid variable, which means it has a regular cycle of brightening and dimming similar to the other stars of its type." These last decades, Polaris has been showing more brightness than dimness. According to Space.com, a group of scientists estimated in 2014 that the Polaris could be about 4.6 times brighter today than it was in ancient times.

You can find the North Star at the end of the "Little Dipper," a constellation which forms a little bear; note the seven stars there, and you will see the North Star at the end. On the other hand, you can find the North Star in the big dipper by drawing a line five times from the two star Dubhe and Merak; you will see Polaris eventually.
