We call it arundhati (alcor) and vashishtha(mizar) Of saptarishi constellation (pan handle of Ursa major)🙏

I was just looking at the sky watching the big dipper then i got the notification of this video 😁💕💕

[@learnthesky]

Fantastic! Did you see the double star?

[@pragatibaishya328]

@@learnthesky yes so clearly...❣❣❣

Perfect as always

[@mikehartman5326]

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.

[@auldteuchter9012]

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.

Thanks Janine! This video is so helpful! 👍🏻

These are the best videos

Good topic- ever doubtful for me, its cleared now. Thank you very much

Great video...didnt knew about the moving star group...learnt something new...thnx👍

[@luismerchan9140]

I love this vid!

[@cgocbya5204]

Thank u this is so informative, well explained.

[@MountainFisher]

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.

[@jram8043]

so good information.. I thought there are only two stars as per our Indian mythology - Mizor is called Vasishta and Alcor is called Arundathi

[@ramachandramoorthy682]

I love u so so much mam.. From India...

[@rickcain988]

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]

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:Alcor=Vashishta:Arundhati

[@j_kz-q8]

Good video. Informative channel. Thank you for making this. Beats all the rampant trash YT shorts

[@penguinluvinman]

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

[@learnthesky]

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]

@@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?

[@kevanhubbard9673]

It's challenging to separate them naked eye but can be done in dark skies.Even tiny binoculars will split them no problem.

[@patclark6032]

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.

[@akilghosh]

So when we look at one star its technically 6 stars. Never new this about big Dipper

[@rockinroller59]

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!

[@kpopkingdom1380]

vashistha and arundhati

[@meisbaconyay7]

It's not a quadruple star system, it's a sextuple star system Mizar A Mizar Ab Mizar B Mizar Bb Alcor A Alcor B

[@RatgenerationX]

Im from the Alcor

[@armencho1]

Bud and Syd from saint seiya :D

[@MountainFisher]

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?

[@learnthesky]

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