Question on Asgard's portrayal in the movie...

[BrollySupersj]

In the movie, the 9 realms, at least Earth and Jottunheim, are planets. So why is Asgard a giant floating....galaxy thing? Why isn't it a planet too?

Because Asgard is not meant to be planetin the film, it's an extra dimensional city on a floating continent.

I see it as being a huge city that broke off of a planet millenniums ago.

 

[Thor The Mighty]

It exists on a small planetoid or fragment.
