Question

What is the relationship of the size of Canopus to the size of Betelgeuse?

Answer 1

Betelgeuse is of course huge, but if you're thinking it's big, watch these videos:

The 2nd video is a little slow in the beginning, but be patient, it's worth it.

Answer 2

Betelgeuse is much larger in terms of volume.  Canopus is about 65 times larger across than the sun, and Betelgeuse is 630 times larger.  This means that Betelgeuse has almost 1000 times as much volume.

However, Betelgeuse is a very un-dense star, so their stellar masses are much more similar.

Answer 3

Thank you for the videos showing the proportions of planets and stars.  I never realized how big Uranus was!

Answer 4

I think that Betelguese is the larger of the two, and perhaps the closest!  Both are classified as "red giants", however Canopus is "F" class and is more white looking, of course that's because it's further away!
