Pentecoastal Elites posted:weak poo poo A fun part about supergiants is that while that star is about 1700 solar radii, it's only about 10 solar masses. Which means that it's got an *average density* of .0083 grams per cubic centimeter. Since most of that mass is down where fusion's happening, the outer portions of the star are a good approximation to vacuum. There's no well-defined surface, the gas just gets less and less dense as you move outwards from the center.

Scrotum Modem posted:The sun is only various yellowish colors when viewed from earth. It's blinding white light when viewed from space It's called a yellow star not because it literally looks yellow but because its emission peak is in the yellow portion of the spectrum. If you add the red and the blue together, it puts out about the same amount of energy in those as it does in the yellow, so it's definitely gonna look white unless as before mentioned it's close to the horizon and you're seeing it through a lot of atmosphere that scatters the blue wavelengths preferentially.
