A red giant star appears red in color due to its cooler surface temperature compared to other stars. The red color is produced by the cooler temperatures causing the star to emit more red light than other colors.
Much Much Much bigger. But the Sun will turn into a Red-Giant in a couple billion years.Your welcome!
Red giant stars emit less light per square meter of surface area than smaller, hotter stars, but their larger size means they have a larger surface area from which to emit light, so they emit more light overall.
The next stage of life for the sun in about 5 billion years is to expand into a red giant. During this phase, the sun will exhaust its core hydrogen fuel and start fusing helium in its core, causing it to expand in size and consume its inner planets. After the red giant phase, the sun will eventually shed its outer layers, forming a planetary nebula, leaving behind a dense core called a white dwarf.

The sun is a star, much like the other stars in the universe. It is a ball of hot, glowing gases that emit light and heat through nuclear fusion reactions at its core. Just like other stars, the sun is born from giant molecular clouds, undergoes a lifecycle, and will eventually evolve into a red giant.
The giant Panda are, well, giant! It is also black and white whereas red pandas are...well, red! And much smaller. Red Pandas resemble racoons!
It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. Light = Energy = Heat = Can make light?
The answer to this question is yes. It can vary, but not very much. Yet, the red giant is the coolest star.
if it is a red giant, which it isn't, it wouldn't change much at all

No, a red giant is a star that has just left the hydrogen burning main sequence and begun the next step, burning helium. As helium undergoes fusion at a much higher temperature than hydrogen undergoes fusion, the star expands dramatically and as it expands its outer layers cool to red heat.
The red glow seen during reentry is caused by the extreme heat generated as the spacecraft's outer surface interacts with the Earth's atmosphere. The heat is a result of air resistance and friction, causing the material on the spacecraft to heat up and emit a red-orange light.
