What color is Polaris described as?

• A. Red
• B. Yellow
• C. Creamy-white
• D. Blue

Answer: (C)

Polaris, also known as the North Star, is often described as having a creamy-white color. This classification stems from its spectral type, which is a F7:Ib supergiant. Stars are characterized by their temperatures and spectral classes, and those classified in the F category typically emit light that appears white with a subtle hint of yellow. Its brightness and hue make it easily recognizable in the night sky, serving as an important navigational reference for centuries. The creamy-white color of Polaris indicates that it is hotter than cooler red or yellow stars, which emit light in the red or yellow spectra respectively. Therefore, Polaris being classified as creamy-white aligns with its actual spectral characteristics and helps in understanding its place within stellar classifications.
