I actually fact checked this and it's true.

Shark facts aside, the fact that Polaris is a ternary system, rather than a single star has completely blown my mind.

    Unlikely Polaris. The luminosity difference between Polaris Aa and the other two is 3 orders of magnitude. Mizar and Alcor (the doublet second from the end of the Big Dipper) has been used for centuries as a vision test. If you can see the doublet, it’s equivalent to 20/20 (or 6/6) on an eye chart.
