Betelgeuse appears red because it is a red supergiant star, which means it has a cooler surface temperature compared to hotter stars. Its surface temperature is around 3,200 Kelvin, emitting more light in the red and infrared wavelengths. This cooler temperature is a result of its advanced stage in stellar evolution, where it has expanded significantly and is nearing the end of its life cycle. The red color is characteristic of such stars, distinguishing them from hotter, blue or white stars.
