    45-67Million Years according to Wikipedia.

    Sharks are hundreds of millions.

    Also somewhat relevant: https://xkcd.com/1342/

        Not directly relevant, but I think Keanu Reaves named his band “Dog Star” because he was “Sirius” about his music career.

    Also from Wikipedia:

    Although appearing to the naked eye as a single point of light, Polaris is a triple star system, composed of the primary, a yellow supergiant designated Polaris Aa, in orbit with a smaller companion, Polaris Ab; the pair is in a wider orbit with Polaris B. The outer pair AB were discovered in August 1779 by William Herschel, where the ‘A’ refers to what is now known to be the Aa/Ab pair.

    I learned something new today. And if I’m reading the details section correctly, while the outer pair of stars are actually older than sharks, it’s the bright star that you can actually see that’s younger than sharks.

      This makes even less sense, how is the heavier thing in the middle younger than the things that orbit it?

        The bigger the star, the brighter it burns

        Also it dies sooner. So any given big star is more likely to be young

        I can explain that but I have to use the only thing available to illustrate.

        So imagine my left testicle here formed before this penis in the middle… And yes it is technically a penis despite the small size, and this testicle-

    Youngest known proto-star is 1300 years old…

    So most species are older than HOPS-315.

    If I understand correctly, it is 2billion years old, but 50million years ago it merged with another star, making it more massive and thereby more bright an visible from earth. Fun fact: Due to it beeing a yellow supergiant it will turn red in a couple of thousand years and then die quiet soon.

    I love it. it feels like Polaris will be there long after this rock is barren and cold, and we can continue to navigate by it in the gay space communism

    Sharks are also older than trees, flowers, Saturn’s rings, and the Atlantic ocean.

      And don’t even get me started on horseshoe crabs. Older than plants, those ones.

        In defence of plants, it takes a highly evolved form of life to be able to do nothing all day and get away with it.

        Those fuckers have like nine different types of eyes. Even that tail is one big photoreceptor! Primitive, my ass - you try surviving crawling around in the mud for 400 million fucking years.
