Want to see something really big? Well watch this. Check out how our own moon compares to the largest star we currently know about , VY Canis Majoris.

  • Ok with this video in mind, I need to ask a maybe stupid question. Is our sun among the smalest stars we know of or is it the same way around? On a scale in sice 1 to 10 where is our sun???

  • @darksneaker2000 As you can see from the video, there are some really big stars, but there aren't that many of them. Our star is pretty average in size when you start counting how many are larger and how many are smaller and how many are about the same size.

  • Why is your version of Sirius yellowish? Sirius is A-class.

  • @1RadicalOne We show it as primarily WHITE but we could have added more blue. We were focused on size more than spectral class.

  • Sort of puts you in perspective hey?...i love the cosmos...just knowing my atoms are from star stuff and will one day return to the cosmos is very cool.

  • yeah the moon is too small. the diameter shud be same as width of north africa :p

  • Want to see something really big? Thats what I said to her.

  • @darksneaker2000 those largest stars are supergiants or hypergiants, in the last phase of their lives before exploding - they weren't nearly that big when they were young. i dont know how much bigger our sun will get right before it explodes, but its diameter will be a lot larger than it is now - maybe out to mercury's orbit or farther... anyone know exactly??

  • hey guys, if you press the snowflake while watching this video, you will learn that it snows in space! im a genius

  • But will it blend?

  • @TheHeavensucks Bizarre question. It makes me happy to know my insignificance.

  • @TonyBtheEG What u mean?

  • So VY Canis Majoris is technically about 5 times wider in diameter than our solar system? Pretty boss.. 'Nuff said
