I guess the question hit the MIT think tank....

The Sun is a G2 class star in size and temperature, Yellowish with a surface temp of 11,000 degbrees. Its closeness and brightness seen from space it appears actually white, and is considered pure white light. The filtration of the air and our eyes give it the yellow tint as we see it, but a prism breaks the "white light" into the spectral colors.

Actually Sun has White color ( mixture of all colors). The reason you see sun as yellow during sunset is the particles in the Atmosphere that absorb shorter wavelenghts and thus let longer wavelenght radiation pass thru. As the sun gets closer to horizon the amount of air it travels is more because of slanted angle so it gets orange / red.

The sun is yellow because it is a middle aged, average star. Eventually (in the far future) it will turn red, and swell up engulfing the entire solar system. Don't worry about this because this is approximately 9 billion years away.

It isn't, really. The color yellow is a purely human interpretation of a collection of radiation that hits the retinae of our eyes and gets processed by our visual cortex.

nimals seem to have some analogous way of discriminating light by some kind of 'coloration' sense, but we have no way to know if their brains actually 'see' the same thing we do when they look at 'yellow' light. Color detection is caused by photosensitive cells called 'cones', and some animals have none of these and would see the Sun as, presumably some shade of grey since there retinae have the black-white sensitive 'rods' instead, and which have a greater light sensitivity.

The sun is not yellow, it's chicken.

It is a function of the surface temp, which is at about 5,500K

h8gwb is right.

The astronomer is also right, but that's kind of answering a different question.
