- What do certain stars look like up close in terms of; colour, and ability to look at.
I have been wondering what certain stars would look like from a closish distance. The kinda size with about the same angular diameter that the Sun has from Earth or bigger. I was mostly wondering about red giants, red supergiants, and red dwarfs.
Like… Would they look red from that sort of distance or white. I mostly ask this because I started this thread (https://www.physicsforums.com/threads/blackbody-colour-of-metals-versus-stars.996533/), and got me thinking perhaps they would look white.
How diffuse their outer limb, edge (whatever it is called) would appear to be?
…. and also, would you be able to look at it? Like… Red dwarfs are really faint. Would you simply be able to stare at one without hurting your eyes. Is the light so spread out across a red giants disk that you would be able to look at it?
I guess I am assuming that all the horrible radiation is taken out, like if you are on a planet like Earth.
Is there anything else interesting about being near these stars.
Thanks so much. I learned so much from my last thread!
