Reply to comment by Fastfaxr in if our sun is the size of an atom, how big would UY Scuti be in comparison? by Major-Apricot69

Really? I’m surprised it’s that big. I knew UY Scuti was several times larger than the sun, but if an atom is that small… Neat!

I worked it out to 84nm (diameter of H ~ 50×10^-12 m, multiplied by 1708), about the thickness of a bacterial flagellum. Much smaller than this commenter's result. I suspect something went wrong with their odd choice of units.

(I actually used 10 nm for width of Hydrogen, much larger than your unit)

Ok that’s just blatant misinformation.

Thats what google report when you search "diameter of hydrogen atom in nanometers"

edit: but googles an idiot

Ah. Alright, that makes much more sense. I assumed it would’ve more likely be somewhere around the size of a small bacterium or virus.
