What is the name of the star that serves as the North Star, found in Ursa Minor?

• A. Polaris
• B. Vega
• C. Antares
• D. Algol

Answer: (A)

Polaris is the name of the star that serves as the North Star, recognized for its unique position nearly directly above the North Pole. This star is located in the constellation Ursa Minor and is significant for navigation and astronomy because it remains relatively fixed in the sky while other stars appear to rotate around it. Its brightness and position make it a reliable reference point for determining direction in the Northern Hemisphere, which is why it has been historically important for travelers and navigators. The other stars mentioned, such as Vega, Antares, and Algol, belong to different constellations and do not hold the same navigational significance as Polaris. Vega is part of the Lyra constellation and is known for being one of the brightest stars. Antares, located in Scorpius, is a red supergiant, while Algol, found in Perseus, is an eclipsing binary star. None of these fulfill the role of the North Star as Polaris does.
