Which star is traditionally used to find North?

• A. Betelgeuse
• B. Sirius
• C. The Pole Star
• D. Antares

Answer: (C)

The Pole Star, also known as Polaris, is traditionally used to find North due to its unique position in the night sky. It is located nearly at the celestial North Pole, making it a reliable point of reference for navigation in the Northern Hemisphere. Observers can determine true North by locating Polaris, as it remains in a fixed position relative to Earth's motion. Other stars, such as Betelgeuse, Sirius, and Antares, do not serve this navigational purpose. While they are prominent in the night sky, their positions change significantly throughout the year and are not aligned to indicate the direction of North. Therefore, Polaris stands out as the only star that provides a constant point of orientation for finding North.
