    What would be good to show is photos of Alcor and Mizar and the slow movement over time. For example photos taken in 1970, 80, 90 and so on. As a boy my brother told me about these stars. He too mentioned they were a test of eyesight. Over time I saw the apparent gaining of separation. So in my lifetime I've seen a perceptible motion of stars. It is this motion that would be cool to see in dated photos. Thank you for this video.

      Yes. I was curious so did a brief trawl and an orbital period of three quarters of a million years was mooted. If you are really keen you could do the calcs -- Wiki "orbital period". Couldn't find an animation, which would be cool, but possibly on the interweb somewhere.

    In the hot climate countries people use to sleep under sky at night. When I was a child I used to lay down for sleep and specially look on the Big Dipper, specially I could notice two stars in Alcor & Mizar. At that time I thought it to be a planet with its moon.

    Funny I was looking at these the other night with my 6 inch scope at 24x. I saw that the little one was red, but at 24x I was able to see three stars. I'm going to check it out again at 50x and 120x later.

    When you say "mizar" is 2 solar masses, does that mean the combined mass of all 4 stars in the system?

    • @learnthesky
      @learnthesky  2 ปีที่แล้ว

      Mizar having 2 solar masses means it has twice the mass of our sun. Astronomers compare star mass with our own sun...in other words: Sun = 1 solar mass

    • @penguinluvinman
      @penguinluvinman 2 ปีที่แล้ว

      @@learnthesky right, but since mizar is actually 4 stars, does it mean the combined mass of all four is 2 solar masses, or like they're an average of 2 solar masses each?

    Listen to yourself my friend. This screams life outside our system. Binary system. Bi means 2. Like a twin system we are in. 2 solar masses. You found life. People are just to programed to understand. Great job.

    • @jursamaj
      @jursamaj 3 หลายเดือนก่อน

      But it's *not* a binary system, it's a sextuple system (6 stars). Neither the number 2 nor the number 6 are evidence of life. Yes, there is likely life elsewhere, but your nonsense isn't an argument for it.

    Mizar is pronounced as Al Meezurr, its arabic for ‘apron’ or to ‘cover’, it is NOT MYZAAR!
    Alcor is also arabic and is pronounced Al Khwaar - the faint one!
    Glory and victory to the Arabs who made immense progress and stride’s with astronomy and all the sciences👍more than half of the star names are arabic!

  • @patclark6032
    @patclark6032 6 หลายเดือนก่อน

    Good video! But you should correct your thumbnail - it shows the 4 star system labeled as Alcor, 2 star as Mizar. Those labels should be reversed. Although that's why I watched your video, so maybe that's clickbait. Otherwise good content.

    Primary, secondary, tertiary, quaternary, quinary, senary, septenary, octonary, nonary, and denary. And you call yourself a teacher? " A sextuple system",😅😂🤣😘. It's ok, I thought it was hexonary and I have 2 Masters. 12 is duodenary and there is no recognized word for 11, possibly eleventy from Tolkien when Bilbo had his eleventy-one birthdate, 111?

      A sextuplet is what astronomers call a system of six stars. It is a real word.
